Very minor bug in SVP Transcoder

For years I've been living with it, but I thought it might by chance as well get fixed.

Whenever a video file, or a list of files, gets transcoded and "When done [Shut down]" is selected, the very last *.SVP.temporary.* won't get deleted before SVP initiates the shutdown.
So when I later look at the files, it's still always there waiting for me to delete it manually.

It might be worth to add the required two lines of code to fix this and spare me like 120 seconds per year. [a thumbs up emoji would be at this position, but this causes the whole website to go Error 500, wth. Took me two weeks to realize this was the culprit...]

...I Just realized I even spent 2 minutes on this bug just by writing this...
