QmlDesigner: Restart overlay update timer on each request

Browse Source 
If timer is not restarted on each request, the update can end up
happening before the next frame has been rendered. This can happen e.g.
at puppet startup, where the delay between first request and first
frame render can easily be more than 16ms.
