plex_exporter_importer.py: no movies in imported collections

[RBeatse]

In which file is the bug? Plex importer exporter

Describe the setup (arguments and their values, how it was run, etc.): standard import with -p collections

Describe what the bug is:

TV shows have the collections and such with no problems that I can see. Movies, however, have the collection created with the poster. However the individual movies are not "in" the collection. If you look at the UI, the lock is yellow as if something is there but nothing is in the field. If I update the tags Field to put the collection name, it is fine but whatever worked on TV Shows is off just a bit in Movies.

Describe what should be happening: The collection Import should not only create the collection with proper name and poster but all of the movies in that collection should be updated to have the proper name tag applied.
