Subject: [PATCH] Avoid run change title process when the title is same
 (#27467)

If user only changed the target branch or just did nothing and clicked
the `Save` button, you will see the change log as following:

This makes no sense, so we should check whether the title is surely
changed before run the `ChangeTitle`.
