Always fallback to the Pypi API when fetching sources & wheels
Previously we randomly encountered issues where the Pypi mirror URLs
wouldn't be correct with packages whos first character is frequently
written in upper case (e.g. SqlAlchemy, MarkupSafe, ...). The Pypi
mirrors are aparently not consistent in the naming of the file locations
which lead to random errors after package version bumps.

By falling back to the API lookup (that we already did for wheels) we
can workaround that situation.
