* HYD-7337 Allow missing session objects in session table during terminate

The chroma-agent.log displays the following trace back during SSI runs, they
result from a missing syslog key in the plug-in name to session object map when
running SessionTable.terminate('syslog') after the session/plug-in teardown
routine has been run.

The missing key should not cause an exception in the log because the session
will have already been successfully deactivated.

  - Except KeyError when deleting 'syslog' from _session map after session
    teardown
