Inverse the behaviour of redirect creation after slug update
When ext:redirects is installed and a user changes a slug, TYPO3 creates new redirects for that slug. When done it shows a JS popup prompting the user if she wants to wants to
- revert the slug change
- revert the redirect creation
For big sites saving a page becomes very slow and in case the user decides to revert the change the time was wasted. For better UX and performance I like to propose to change the behavior and ask what to do before the redirects are getting created.
