Providers and dependants in dataDepend do not get cleaned correctly up when surrounding scope gets destroyed.

Problem arises in procDef instance and called process definitions tabs.

ie. the following callback should get cleaned up correctly instead of leaking

function MyController($scope) {
$scope.data.get('asd', function(asd)

{ console.log(asd); }

);
}

instead, the provided factory is not cleaned up at all and 'asd' is printed out once for each time the controller got initialized
