fix(findState) for undefined stateName

[george-i]

In combination with angular translate, sometimes 'stateName' is undefined.

Returning undefined is the expected behavior. Can you explain a bit more about why this is necessary, or show some code that demonstrates the problem you're trying to solve?

angular-translate -> https://github.com/angular-translate/angular-translate
I believe that angular-translate has a conflict with ui-router, at least in my configuration.
The 'stateName' argument is undefined when is passed to 'findState' function.
The highlighted code throws the error.

  function findState(stateOrName, base) {
    var isStr = isString(stateOrName),
        name  = isStr ? stateOrName : stateOrName.name,
        path  = isRelative(name);

In Google Chrome developer console this is the message:

TypeError: Cannot read property 'name' of undefined

Says "Not Found". I think I get the gist from the comment though. I was just confused because I don't see what angular-translate has to do with it.

oops, yeah I didn't know run.plnkr.co times out.

A colleague corrected me; the issue wasn't with the translation module, but:

'when there is a navigation point which has no ui-state'

Thanks for fixing it.
