Merge pull request #9729 from sean-m-sullivan/project_update_changed

Update changed logic on project update

SUMMARY
Related to #8349
Found the inventory source does not have a way to track it, so did not do that part.
However scm revision is tracked for project update, as we already retrieve this data when looking for the existing item and waiting, put in logic to compare the two values when wait is true.
Also double checked the integration tests, and believe this should not change them, as its looking for result is success not changed in all but the first update.
