Paygen: Don't fail build if Payload tests can't be scheduled.

For now, we just eat the error if we can't schedule the payload test
suite. I'll keep the bug open, and start warning on test schedule
failures after Yu-Ju's CL:200682 lands.

That will help, because the type of an exception raised in a
background process is currently lost. Her change will preserve it so we
can decide if we should warn or not.

TEST=pylint + Unittests
