Changing a Google Calendar event title creates a new task in weekplan instead of updating the existing task

This is very minor:

• You have an event on a Google Calendar. 
• On Google Calendar, you modify the event's title.
• In Weekplan, rather than updating the synchronized task's title, a new task is created.

Would be nice if the event-task synchronization used the Google Calendar event ID rather than matching on the title, so that you would end up with new tasks each time that you modify an event name.
