fixes trakt.tv movie/tv scrobbling problem

Fixes movie scrobbling which was broken.  Initially it was passing
"moviename (year)" in title field when it should only be passing
"moviename".

Removed call to format_tvshow_episode() and format_label_movie() as
these can't manipulate title and scrobble properly.

Enables scrobbling of tv/movies when 'Enable MetaData' in settings is
off.  I want to scrobble but not pull all metadata as it's too slow on
my connection.
