Resets the cache used for glib.global.getUserSpecialDir, so
that the latest on-disk version is used. Call this only
if you just changed the data on disk yourself.
Due to thread safety issues this may cause leaking of strings
that were previously returned from glib.global.getUserSpecialDir
that can't be freed. We ensure to only leak the data for
the directories that actually changed value though.
