Cannot detect excluded addons in strm files

[helviojr]

I am not sure if it was a Matrix change, but since moved to Matrix, the addon exclusions is no longer working for strm files. It seems it compares the excluded addon names with the video source from videosource() = xbmc.getInfoLabel('Player.Folderpath') and that property now returns the video filename, even if it is a strm file.

It should read the .strm file content where we can find the actual video url, and, if that's the case, the name of the used addon.
