This commit saves all seasons from watched shows into realm. But is not a good idea to get all the seasons everytime the app opens.

A better approach would be, get all data when the app opens for the first time, then, only get data of watched progress/next episode, and add a way so the user can force to update all data again.

This will work and consumes less data than now, but we need some logic when there is a new season available, to get data from that new season!
