If there is not a state with '/' defined, infinite loop

Seems like if there is not a state with a url of '/' then the states will go in an infinite loop.

I did some testing, and it seems that the / state cannot be an abstract parent state.

App Bootstraps; url is ""
-> check rules against ""; only otherwise('/home') matches
-> $location.path('/home')
-> check rules against "/home"; match 'home' and transitionTo('home') (Transition 1)
-> Transition 1) $stateChangeStart.preventDefault()
-> transitionTo('login') (Transition 2)
-> Transition 2) $stateChangeStart, not prevented; goes to async portion
-> Stack popped until we get back to...
-> Transition 1) $stateChangeStart.defaultPrevented === true, so call $urlRouter.update()
-> $location.path() is reset to the last know url, ""
cycle starts

I can't seem to create a failing unit test. Perhaps this is due to the mocks behaving differently.

edit: Thanks to the #600 (comment) by @filipesilva I was able to create a failing test case.

Also interesting: the plunker works if you downgrade angular to 1.3.3 or earlier. 1.3.4 and above exhibit the infinite digest.

I'm glad to hear I was of help @christopherthielen. Great job on the fix!
