DoubleCallGuard mixin
All navigation methods are built around the idea that when we want to navigate somewhere, it is navigate to somewhere from the current page.
Unexpected things may happen if we allow > 1 calls from any of the navigation
methods. For example, calling pushNext twice from the same page doesn't really
make sense. pushNext means push the page adjacent to the current page.
What does it mean to push the adjacent page twice?
This guard method is here to prevent us from going down the rabbit hole that is the subjective interpretation of the aforementioned point.
If either of these methods below are called, the call guard will lock the navigation from happening from the same instance resetDoubleCallGuard is called.
Forward: pushNext, pushFor, pushFirst, pushFirstThenFor
Backward: popCurrent, popFor
The guard will reset when the future from next completes.
initializeRoutes does not count as a navigation method and is not guarded.
