Fails to find episode mid-season.

[AnalogMan151]

Running on a directory it finds and matches the first 17 episodes just fine, then fails for episodes 18-24. So far this has only happened on this one specific series, I have been able to successfully process other series greater than 17 episodes. This also happens when specifying the TVDB ID manually. This only happens with TVDB, works fine with TVMaze.

Since posting this I have run into a few more series that are affected and have found the cause. If an episode lacks an episode description (in the example show in the OP, Jujutsu Kaisen, episodes 18-24 have no summaries) then the matching will fail.

[AnalogMan151]

Here's the issue: https://github.com/jkwill87/mnamer/blob/feea26aee7e6329c9c7ca79d4d892ae8332f9b86/mnamer/providers.py#L279-L282 If a synopsis is blank you set it to None but then the replace functions after error on a None object. Changing it to this works fine: synopsis=(entry["overview"] or "")

Thanks @AnalogMan151

I have added this to the MR i have for fixing issue #144
