onBefore hook returning Promise<TargetState> does not work.

[grant77]

If I return just TargetState it works. But if the I return the TargetState from within a promise it does not. My hook looks like this

    function hook(transition) {
        var target = transition.router.stateService.target,
            targetState = transition.targetState(),
            targetStateInternal = targetState.state(),
            targetStateData = targetStateInternal && targetStateInternal.data,
            allowAnonymous = targetStateData && targetStateData.allowAnonymous;

        // Returning right here outside of promise will work.  Ie:
        // return target(loginStateName, { redirectTo: targetState.name(), redirectParams: targetState.params() });

        return !allowAnonymous ? signInManager.isSignedIn().then(noop, error) : null;

        function error() {
            return target(loginStateName, {
                redirectTo: targetState.name(),
                redirectParams: targetState.params()
            });
        }
    }

Nevermind. I did something to address this bug #2676 and it caused this bug.
