Don't do full Plex pull for every sync

[steezeburger]

I think it's currently syncing the entirety of the movies list. Can we page by last synced date?

Ope, comment in my code:

"""
Sync Oscarr's database with the movies on the Plex.
Stops syncing when we get to a movie that was added
before the latest movie in the database.

Unfortunately the Plex API doesn't allow us to filter
by addedAt, so we have to get a page of movies.

Closing for now, but might look into optimizing this sync later on. It's not terrible yet -- just a small cpu spike every 5 min
