Fix typo errors which caused rollback

aea6e011c13bb183d1bbc74b1f30d240e976ccb7 mentions a typo caused the rollback. I manual review and local tests of the externs brought me to these corrections. However, if this isn't the correct change, can someone chime in with more details?
The comment was that this line should have been

`ui.router.$state.state.GoOptions_;`

(putting the $ on the first state in the chain) instead of what it was originally:

`ui.router.state.$state.GoOptions_;`

Or maybe what you have here is more correct.
