fix(preview): Do not try to parse M3U files as MP3Fix/mp3_regex

By default, the MP3 audio files get the mimetype `audio/mpeg` and the M3U and
M3U8 playlist files get the mimetype `audio/mpegurl`. PreviewManager had such
a problem that it registered the MP3 preview provider with a regular
expression which matched also the M3U files. This caused an error message to
be logged on the info (1) level for each M3U file every time a folder with
such files was viewed: "Error while getting cover from mp3 file:
File /path/to/some/playlist.m3u is not mpeg/audio!".
