Fred Liu b3886652ab Fix navigation jump on multi-tap
Summary:
On iOS, if a non-selected breadcrumb is tapped multiple times, the navigator will transition to the tapped breadcrumb, then back to the previously selected breadcrumb. Then, when another breadcrumb is tapped, it would go to the previously multi-tapped breadcrumb.

This seems to be because transitions are queued when they shouldn't be. I've reverted to the way it was before PR 8701, but added a `transitionQueue.length === 0`. This should solve the race condition from 8701, ensuring all transitions in the queue are flushed in sequence, and thus landing on the finally tapped one.
