More clear feedback on typo in model class setup.

[dereuromark]

I had a typo in the model class BitmaskedRecords and things appeared to work fine, even though the model was never loaded.

		$this->loadComponent('Search.Search', [
			'actions' => ['bitmaskSearch'],
			'queryStringWhitelist' => ['type'],
			'modelClass' => 'Sandbox.BitmaskedRecords',
		]);

and I didnt notice that things are wrong, only when looking closer to the reason why the reset button would not show.
With this info it should be clear that a configured value would need to exist or should otherwise be left null/empty.

If the issue was about the model not being found/loaded then changes should be done to the try/catch block above which has the fetchTable() call, not when checking for the behavior.
