gstelementfactory: Fix missing features in case a feature moves to another filename

In case a plugin filename was renamed with the plugin being in the registry cache
the features where not loaded after the rename:

Cache of old/gone filename was loaded, features added
New filename was loaded, features where not added because
they were already found in the registry.
In the end stale cache entries for files which are no longer there
are removed, including the wanted features.
The cache gets updated without the features.

Fix this by also checking at (2) that the found feature is from the loaded plugin
and not from some stale cache entry.

This affected directsoundsink where libgstdirectsoundsink.dll was renamed
to libgstdirectsound.dll, losing the directsoundsink element in the process.
