QMimeDatabase: Fix handling of duplicate mimetype definitions (2/2).

Browse Source 
7721c3d27c fixed the case where two similar definitions are in the same
directory. This commit fixes the case where two similar definitions are
in different directories, both in the search path (GenericDataLocation).

If the file extension gives us the same mimetype twice, there's no conflict,
i.e. no reason to fallback to determination from contents.
