feat(bank-sdk): Always call the cancelled result when the user leaves…

… the host fragment via a back action

The top and bottom navigation bar back/close buttons trigger a back button press to allow the
nav graph to handle back navigation the same way for our navbars as for the system back button.

For popping the back stack a back button press is triggered as well.
