Fix auto-rename double-episode bug and add 62 rename tests

Browse Source 
Bug fixed: When a folder already contained the same episode token as
the source file (e.g. Show.S01E05.720p-4sf + s01e05.mkv), the episode
was inserted a second time producing Show.S01E05.720p.S01E05-4sf.

Root cause: The replace produced an identical string, the equality check
fell through to the suffix-insert branch which added the token again.
Fix: Use regex.test() first, then always apply the replacement when
an episode pattern exists in the folder name.
