[3.7] bpo-33169: Remove values of `None` from sys.path_importer_cache when invalidating caches (GH-6402) (GH-6403)
 
An entry of None in sys.path_importer_cache represents a negative/missing finder for a path, so clearing it out makes sense.
(cherry picked from commit 9e2be60634914f23db2ae5624e4acc9335bf5fea)
