Create a new isolated scope when a module is compiled

[emanuelcostea]

If the module has an isolated scope then any properties that are set on the $rootScope can't be used.
To create a new scope we need to use $scope.$new(true) that returns a new $scope object. True means that is isolated and will not inherit any properties.

Docs about $new https://docs.angularjs.org/api/ng/type/$rootScope.Scope#$new

@cemycc Using the newly created isolated scope on $rootScope as a fallback, however it doesn't trigger the $destroy event we need to clear subscriptions when a module is destroyed.
