FileCollection does not return simple playlist with .m3u8 extension

[cezary-zemis]

Bug report

Describe the bug

Here is a clear and concise description of what the problem is:

Kodi 21 by default creates simple music playlist as UTF-8 files with .m3u8 extension. Such a playlist is visible in UI, but is not listed by external tools, such as Chorus 2 or Yast. Probable reason in that API function FileCollection does not return such a playlist. If the file's extension is changed to .m3u, it is properly listed.

Expected Behavior

Here is a clear and concise description of what was expected to happen:

Playlist with either .m3u or .m3u8 extension are returned by FileCollection.

Actual Behavior

Only playlist with .m3u extensions are returned.

Possible Fix

To Reproduce

Steps to reproduce the behavior:

1. using Kodi 21 create a simple music playlist containing one or more tracks
2. save the playlist using 'a' as its name
3. open Chorus 2 web interface and navigate to Browser → Music → Playlists
