[BUG] Subtitle files with 3 chars language code are not imported

[juandbc]

Describe the bug
Subtitle files with 3 characters code for languages (spa, eng, etc) are skipped and deleted

To Reproduce
Steps to reproduce the behavior:

1. Copy a movie or show with subtitles
2. Click on the 'import movie/show' option in the respective module
3. Open the file explorer, and only the video file is imported
4. See error in logs

Expected behavior
When the videos are imported, it should import the subtitles as well. For example:
