Making sure this movie isn't a repeat

Points: 1

TODOs:

[ ] Check any new movies being entered into the database against other movies using their TMDB ID number

Description: Confirm that there are no duplicate movies.

Notes: We need to make sure we are only putting in each movie once. This will make sure we can't have the same movie back to back when the game is live. Depends on https://github.com/passiondynamics/cast-le-backend/issues/11
