Partial file crash

[baoizbak]

Expected behaviour

Caspar to stop the current consumer or load the background clip if it's there. Older version of caspar just stop playing the clip (Froze). Something like this we can detect and tell caspar to load a new clip. There are unforseen circumstance that we failed to check for partial files.

Current behaviour

When playing a partial file, caspar will crash when it reached to the end.

Steps to reproduce

1. Play any partial file (incomplete download)
3. ...

This seems like it's linked to #1451 and #1460, may even be the exact same issue as #1460
