Fixed issue matching list of plex object to tmdb.

We have a Plex function that allows us to input a tmdb object and a plex
search result too see if the tmdb object has anything similar when
searching in plex.
Fixed an issue where plex returned a list of items. This list is now
mapped over each list element.
