Fix 500 error updating mirror URLs for projects

Updating the mirror URL with an empty URL should just render the mirror page with the flash message stating that the URL can't be blank. At the moment we throw an error 500 if the old URL had some import data.

Fixes https://gitlab.com/gitlab-org/gitlab-ee/issues/1082

See merge request !780

We have to be consistent as we have already removed it but not completely(https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/4099/).

Closes todos for a merge request when the MR is accepted via the API by the MR assignee.

## Are there points in the code the reviewer needs to double check?

Please review refresh service test changes to see if they are correct - I think in those cases, the todos should actually be cleared instead of left pending.

## Why was this MR needed?

To make the API behavior consistent with the UI behavior (accepting your own MRs closes the todo item and prevents them from piling up).

Closes #22477
