Don't use analyzed show episode title unconditionally
The current behavior is to analyze a video title based on the
<show name> <SXXEXX> <episode title> pattern.
The problem is, there are many patterns that we don't handle, and we are likely to end up with invalid title overriding the sanitized title.
For now (0.7.x), and so that the iOS application stops getting slaughtered in reviews
- Stop using the extracted title unconditionally
Once this is done, and for the long term fix (not necessarily 0.7.x):
- Add an extra 'guessed_title'/'title' in the ShowEpisode table
- Insert the pattern based title in that field, by keeping the media title unchanged (ie. just use the title sanitizer result)
