rebase: only change self.state when collapsing in _finishrebase
When the code executes to _finishrebase, self.state should be populated with
correct destinations and do not need to be written to a node. The code was
introduced by 8dc45c9059, which seems to avoid setting state values to None
but it didn't provide more details.
