[PATCH] gnu: Fix propagations of python-prompt-toolkit-2.

Hello Guix!
On Guix System
guix ecab53c repository URL: https://git.savannah.gnu.org/git/guix.git branch: master commit: ecab53c320b1584a08f811b17a92bd9a50a50ff3
it's impossible to install jupyter in a new profile because it tries to propagate two different versions of python-ipython, you should be able to reproduce with:
guix package -p /tmp/tmp-prof -i jupyter
I believe since 32ba87c14fd5e5b54d95211cd9a159d568ce7c67 many packages whose tests depend on version python-prompt-toolkit at version 2 yield conflicts when installed in a profile.
I attached a patch to propagate the right versions.

Hi everybody, a little update about this patch,
I just found out that it doesn't actually fix the problem: the requirement for prompt 2 is enforced also at runtime.
The output of guix package _without_ my patch is:

$ guix package -p /tmp/tmp-profile -i jupyterThe following package will be installed: jupyter 1.0.0
guix package: error: profile contains conflicting entries for python-ipythonguix package: error: first entry: python-ipython@7.9.0 /gnu/store/z0yarar134q6sziqncjdlfg2h2w5b2yh-python-ipython-7.9.0guix package: error: ... propagated from python-ipywidgets@7.5.1guix package: error: ... propagated from jupyter@1.0.0guix package: error: second entry: python-ipython@7.9.0 /gnu/store/avmg5jd7kccchxadsd9c7zq0p3shlk3w-python-ipython-7.9.0guix package: error: ... propagated from python-qtconsole@4.4.3guix package: error: ... propagated from jupyter@1.0.0hint: You cannot have two different versions or variants of `jupyter' in the same profile.

With my patch applied it is possible to install jupyter without conflicts but when started it crashes asking for prompt-toolkit at version 2. The conflict seems to be caused because:
- /gnu/store/avmg5jd7kccchxadsd9c7zq0p3shlk3w-python-ipython-7.9.0depends on python-prompt-toolkit@3.0.5
- /gnu/store/z0yarar134q6sziqncjdlfg2h2w5b2yh-python-ipython-7.9.0depends on python-prompt-toolkit@2.0.7
Please ignore the previous patch, I apologize for the noise. I'm opening an actual bug report and I'll start working on a fix ASAP.

Giacomo

Hi Edouard,
thank you for providing a fix. I think it’s too complicated, though.Using prompt-toolkit-2-instead-of-prompt-toolkit everywhere does notseem like an elegant solution.
I pushed a different fix with commit 7146c8c75d.
