Fix broken uninstallation by a bogus downstream patch

Browse Source 
In pip 21.2, the Distribution here is a wrapper around the regular Distribution.
It has a limited set of API defined by the BaseDistribution protocol.
dist_location() uses the project_name attribute under the hood --
and that is not part of the API.

If we ever upstream this, we should make this check a property of BaseDistribution.
But, for now, we hotfix it by accessing the private wrapped Distribution object directly.
Yes, this is ugly.
