ergo(config): handling different redirects from siblings

[btford]

Imagine:

<div router-view-port="left"></div>
<div router-view-port="right"></div>

If left's config looks like: { path: 'foo', redirectTo: 'bar' } and right's config looks like: { path: 'foo', redirectTo: 'baz' }, what should happen?

I think at config-time, whichever is registered second should throw.

As cyclic definition isn't allowed, I'd assume the right way about this is to have a method checking the config for such violation and throwing an exception.
