tst_qdeclarativetextedit timeouts delegateloading

This can be repeated every time. Actually I can't even get it passing a single time. So it's not even flaky.

In the CI it doesn't fail, so it might also be that these new templates we are about to take into use are incorrectly configured. What could cause this though?

FAIL!  : tst_qdeclarativetextedit::delegateLoading(pass) QTestLib: This test case check ("(((view->rootObject())))") failed because the requested timeout (5000 ms) was too short, 5100 ms would have been sufficient this time.
