Title: Fix the merge notification email not being sent

I broke the merge notification emails in the 6.7.* branch.

This commit restore the email notification for merged MR. The 'author_id_of_changes' attribute was always nil (as this attribute is not persisted to the database). Also there was no tests for the merge email notification — tests have been added.

Fix #6605
