Subject: [PATCH] Fix auto-rename race in hybrid extraction missing MKV files

During hybrid extraction, files can finish extracting between the
auto-rename scan and MKV-move, causing them to be moved to the MKV
library dir with their original scene names (e.g. awa-diethundermans03e21hd.mkv).

Add a post-MKV-move auto-rename pass on the MKV library directory to
catch these stragglers and rename them to the proper folder-based name.
