tv_shows record not deleted when deleting show

Before submitting your issue:

Enable debug logging from settings in SiCKRAGE then try and reproduce the error

Summary
When deleting a show it appears to work correctly at first, without any errors but after restarting Sickrage the show is back in the list but without episode info, images and so on.

Branch/Commit
SR Version: master / 9.4.222

OS
Windows Server 2016 / Python 3.7.4

Steps to reproduce

1. Delete a show from SickRage
2. Restart SickRage
3. Refresh show list
4. Show is still there but empty

What is the current bug behavior?
All records related to the show gets deleted in the DB as they should except for the tv_shows table record. I did some minor throubleshooting and tried to delete a faulty record manually, but was blocked due to foreign key missmatch with imdb_info.

What is the expected correct behavior?
The tv_shows record actually gets deleted.
