temparary backaward compatibility patch for Controller.init

- feedback relies on *Controller.init to be called when a Controller is
being created. this with previous angular refactoring this is not happening
in angular any more. To make it easier for feedback to transition, this
change makes $become call controller's init method if present.

- call to Controller.init from $route.updateRoute was removed. this was
left there by accident during the previous refactoring.
