Properly handle the planner state

This does two independent things:

It sets the planner state early enough so the appropriate
default profile for the planner is created (without
safety stop).

Upon cancelling the planner, it resets the profile widget
to profile more (rather than planner) as otherwise upon
the next change into the planner the planner model is
not properly initialized.
