Write a change message when approvals are removed

If the approvals of a reviewer are removed (e.g. by the project owner)
this is now recorded as a change message so that it later can be seen
who removed the approvals.

This change only affects removing reviewers on ChangeScreen2. If a
reviewer is removed on the old change screen there is still no
message.
