GNOME Builder: Global search, autocompletion, documentation don't work

Various features described in GNOME Builder documentation (https://builder.readthedocs.io/en/latest/exploring.html)don't seem to work, even though their corresponding extensions are enabled (in Settings → Extensions).

So far, I've only identified Global search, autocompletion, documentation on hover. I tried these in Python code only.

I assumed these features are failing for the same reason, so I'm reporting them together.

## Steps to reproduce: Search for a function in your Python project

1. Start GNOME Builder

2. Click on the "Select a Folder..." button

3. Locate the folder of your project and click "Open"

4. Press Ctrl + . to focus the search box

5. Start typing the name of a function you know is defined in the project source code

## Expected result

You see the function suggested in the results.

## Unexpected result

The suggested results don't include the function. Searching only seems to suggest filenames that include your search terms; definitions in the source code, like classes and functions, seem to be excluded.

## Steps to reproduce: Autocompletion in a Python file

1. Open a Python file

2. Type "Hello". (that's hello in double quotes, followed by a dot)

## Expected result

A list of methods for string objects is displayed after you type the dot.

## Unexpected result

The list is not displayed at all.

## Steps to reproduce: Documentation on hovering over a Python method

1. Open a Python file

2. Type "Hello {}".format("World")

3. Hover over the "format" method or place the caret on it and press F2

## Expected result

A box appears over the method displaying its documentation.

## Unexpected result

The box is not displayed at all.

## System information

guix 08d8c2d

gnome-builder 3.36.1

## Additional information

I see the following output when I start gnome-builder from a terminal:

```

$ gnome-builder

sh: getent: command not found

Hello Luis,

After long trial and error I have failed to find a way of enabling this

feature. Getting the necessary environment variables into GNOME

Builder is doable, albeit not without issues. In particular, naively

setting GI_TYPELIB_PATH from build – which would normally be the sane

thing to do – sets you up for a runtime error. However, even after

you've somehow weasled the correct paths into all the environment

variables, getting them propagated into the IDE workers is a nightmare,

that I wish no one. I tried deleting the line, that unsets the

environment, I tried explicitly setting it to false; nothing works.

If someone else wants to take this bug, go ahead, otherwise I suggest

dropping Python support from our builds of GNOME Builder so as to not

cause confusion in such a manner.

Regards,

Leo

Please add this as a comment above “-Dplugin_jedi=false” (refer to the

bug by URL so there’s no ambiguity).

Otherwise LGTM, thanks!

I feel like a side comment as in v2 would be wiser, so as to not

disrupt the sentence started before and to keep the sentiment, that it

should be enabled once someone has figured out, how to do so.

Of course, the side does not offer enough space for the full URL, so

that's bad. Would it suffice to add the URL to the commit message, so

one could `git blame` me?
