There is currently no way to dissociate subtitles files from a scene.

[cj12312021]

Describe the bug Once a subtitle file gets associated with a scene, there is currently no way to disassociate the file from the scene.

To Reproduce Steps to reproduce the behavior:

1. Scan a scene with a correctly named subtitle file
2. Confirm the subtitle was registered to the scene
3. Remove or rename the subtitle file
4. Rescan folder

Expected behavior When a subtitle file is extracted, a rescan should detect that and remove the association to the removed subtitle from the scene.
