Rerun fails when run name is too long

[donkirkby]

I tried rerunning a sample with a long name, and got this error:

Traceback:

File "/opt/venv_kive/lib/python3.6/site-packages/django/db/backends/utils.py" in _execute
  84.                 return self.cursor.execute(sql, params)

The above exception (value too long for type character varying(60)
) was the direct cause of the following exception:

Exception Type: DataError at /api/containerruns/
Exception Value: value too long for type character varying(60)

It probably tried to add (Rerun) to the end of the name. I guess we should trim the end to be something like "A really long name that...(Rerun)".
