Requesting already existing movies is possible

[danshilm]

Describe the bug
Movies in libraries that use the TMDB agent are not parsed properly and don't show up as Available.
This results in being able to request movies that are already present in Radarr and the Plex library which in turn results in an error in Overseer and a Invalid request Validation failed: -- TmdbId: This movie has already been added in Radarr.

Are you on latest or develop branch?
sctx/overseerr:latest

To Reproduce
Steps to reproduce the behavior:

1. Request a movie that's already present in Radarr.
2. Check the logs.

Expected behavior
Ideally, the movie shouldn't be able to be requested if it's already present in Radarr/Plex since the Plex Library Scan would mark the movie as already Available.

We currently do not have Radarr/Sonarr sync so we have updated the logging to make things a little bit more clear for the user.

If your Plex sync is working, Overseerr should mark it as Available and a user should not be able to request a movie that already exists.

I believe this is a non-issue at this point. Going to close this for now.
