[BUG]: Incorrect return type hint of Phalcon\Mvc\Model::getEventsManager()

[sergeyklay]

The current implementation of Phalcon\Mvc\Model::getEventsManager implies that method must return a Phalcon\Events\ManagerInterface instance:

cphalcon/phalcon/Mvc/Model.zep

Lines 1702 to 1705 in 930fc08

	public function getEventsManager() -> <EventsManagerInterface>
	{
	return this->modelsManager->getCustomEventsManager(this);
	}

however, Manger::getCustomEventsManager may return boolean FALSE:

cphalcon/phalcon/Mvc/Model/Manager.zep

Lines 199 to 208 in 3691c7f

	public function getCustomEventsManager(<ModelInterface> model) -> <EventsManagerInterface> | bool
	{
	var eventsManager;
	if !fetch eventsManager, this->customEventsManager[get_class_lower(model)] {
	return false;
	}
	return eventsManager;
	}

This leads to a fatal error:

PHP Fatal error:
Return value of Phalcon\Mvc\Model::getEventsManager()
must implement interface Phalcon\Events\ManagerInterface,
bool returned in Unknown on line 0
