MediaWrapper: add cond to udpateMeta for title

If libvlc doesn't have any meta for title it will provide the filename.
This can be problematic with m3u8 #EXTINF that provides a title.
This adds a check when updating the title meta. If the libvlc title
provided is equal to the filename then it will proritize the
medialibrary title.

Fixes #2722
