Don't notify us someone stopped working
The WorkLog plugin has the bad habit of notifying everyone that someone has stopped working on some ticket. The message looks like "hours changed, totalhours changed, Hours recorded automatically by the worklog plugin."
This little patch will make sure no notifications are sent for such events.
If you have any issues, create a new ticket.

If you don't want to receive "Hours recorded automatically by the worklog plugin." email every time someone stops working on a ticket.
