[gnome-music/wip/mschraal/filter-playlists] query: Filter out on-disk playlist formats

[Marinus Schraal <mschraal src gnome org>]

commit 356c7e9afad518d80915cfc91a07329f23f9c95a

    query: Filter out on-disk playlist formats
    
    Filter out .m3u, .m3u8 and .pls playlist. They show up inconsistently
    and there is no good use case for showing them at this time.
    
    Closes: #72, #151
