Make job name in sorenson dashboard shorter

[switowski]

Right now, we send the whole filepath and preset id to sorenson, but sorenson dashboard displays only 50 characters of the job name.
Due to the very long movies' titles, it end up like this:

CDS File:_FILE_LOCATION_PATH_STARTS_HERE_/sorenso
CDS File:_FILE_LOCATION_PATH_STARTS_HERE_/sorenso
CDS File:_FILE_LOCATION_PATH_STARTS_HERE_/sorenso

which is not helpful at all if want to find a particular task (the real path is replaced with _FILE_LOCATION_PATH_STARTS_HERE_ but I think you get the point).

Let's think of a better name.
