[fix bug 1083736] Add emit with query on load.

This should fix bug [1083736](https://bugzilla.mozilla.org/show_bug.cgi?id=1083736).

I'm fairly new to angular so if this is bonkers in some way don't hesitate to comment.

So to use the [`.$emit()`](https://docs.angularjs.org/api/ng/type/$rootScope.Scope#$emit) to send a message from the filters controller to the jobs controller you need to do that either upwards or downwards the scope and since the jobs controller was neither the in the child scope or parent scope I added it to make the `.$emit()` possible.
