Closes elastic#184646

## Summary

- updated the code to include additional validation, ensuring that
updateIncident({...}) is not called when incidentToBeClosed object is
empty, this ensured that cases where getIncident or
getIncidentByCorrelationId return an empty object are properly handled.

- small change in Run connector flyout > configuration tab: fixed typo,
"read-only" instead of "readonly"

(cherry picked from commit 5d77a1a)
