Value passed to domAutomationController.setAutomationId is no longer looked at (only compared against MSG_ROUTING_NONE).
Almost all calls to domAutomationController.send are prefix with a call to domAutomationController.setAutomationId.
Let's try to just remove domAutomationController.setAutomationId.
