Ignore missing proxy when removing grid-type batch jobs. #3072
Ignore missing proxy when removing grid-type batch jobs. #3072

In the HTCondor-CE, we can have a grid job's sandbox disappear before
the gridmanager picks up the job for removal. The gridmanager
immeidately puts the job on hold because it can't read the proxy. But we
don't need the proxy to remove the job.
