Embedded pulsar and interactive tool job finish fails

[galaxyproject-sentryintegration]

The job is still running on the pulsar side, but it's been stopped (either by the user or the walltime). This means we get https://github.com/galaxyproject/pulsar/blob/master/pulsar/manager_endpoint_util.py#L30 and lack the output contents.

It's probably OK to kill the remote job if it is still running, then get the real full status.
