[ui-router] Redirect to child view infinite loop

[hjylewis]

One might want to set up a state to redirect to a sub-state using middleware.
Say, /docs always redirects to /docs/getting-started.

When a simple this.redirectTo('parent.child') middleware is written and called when routing to the parent state, it results in an infinite loop.

Example: (caution: crashes page)

In this example, there are state one with sub-states, one.one and one.two and state two. Presently, the only middleware used is one that simply calls this.next().

If one changes the middleware at the two lines commented with // Change to 'redirect' middleware to the redirect middleware, one expects that clicking the one and two links redirect to sub-state one.one. The two link performs as expected, but clicking the one link causes an infinite loop.

@oldtimeguitarguy The issue is still present in the plunkr link for me. Strange.. Did you make sure to change the lines commented with // Change to 'redirect' middleware?

My pull request added functionality unrelated to this issue.

This one is pretty tricky. I worked on it a bit tonight and didn't really get anywhere.
