Update full-text search index when moving issues
When moving issues, we do several updates to the new issue within an
outer transaction. This caused saved_changes
to return only the
changes of the latest update even if more changes were committed.
This meant #update_search_data!
wasn't run even though we saved the
title and description of the issue.

Fixing missing data will be done in a separate MR.
