Fixes jazzband#2118.

Now, with this in requirements.txt:

    django-debug-toolbar
    django-geojson
    wagtail>=4.2,<4.3

I get:

    $ env/bin/pip-compile --resolver=backtracking --generate-hashes --allow-unsafe --output-file requirements.txt requirements.in
        error: subprocess-exited-with-error

        × python setup.py egg_info did not run successfully.

        note: This error originates from a subprocess, and is likely not a problem with pip.
    Discarding django-geojson (from -r requirements.in (line 11)) to proceed the resolution.
    It looks like it has a release with broken metadata, causing this resolver to fail.
    You may try to pin that package's version (probably to a recent one), so the resolver doesn't consider the broken release.

The exception is still shown. Also we log a warning to tell the user the package was discarded.

The way to find the offending pacakge is crude (regex in error message string).

When the regex search for package name fails, we re-raise the error so no requirements file is generated.

In that case we log an error, which is hopefully helpful.
