rebaseline-cl: continue on if there are no jobs to trigger

The purpose of this CL is to fix  http://crbug.com/726078 ,
which is a bug accidentally added in
https://codereview.chromium.org/2890373003 - this CL also
changes the unit tests to set --trigger-jobs to be True by
default in most tests (which is better since it's True by
default if not explicitly specified).
