navigation fails if parent state requires stateparams

[hannadrehman]

few problems in this module.

1. while using angular components, previous/parent state is dependent on route params. so when you go back to those states the state params are always set to null or removed.
2. in angular components, if you are using dynamic labels from the component controller scope variables, when you move to next state you lose the dynamic label of the parent state.
   3.label does not use $stateparams to generate dynamic names from it.

if these issues are resolved this would help me save a lot of pain in my project
