Successfully converted file is not moved from cache to the actual storage directory.

[dave105010]

The successfully converted file is not being moved from cache to actual storage directory.

Rails version: 6.1.3.1 Ruby version: 2.6

Steps:

• Let's say file_name.mov (non-mp4) file is uploaded.
• It's encoded into mp4 through carrierwave::video and ffmpeg.
• conversion is successfully completed.
• the file is in the cache directory as file_name.mp4 and the file plays and works correctly.
• file_name.mov in the storage directory is never removed or replaced with the mp4 file.
• mp4 file stays in the cache file forever even after the conversion is done.
