fix async call order in configure audio

This error was appearing in audio gear configuration when clicking Next button in
select & test audio gear step. on this button click the program executed
an event listener on input channel check box click (programmatically) and
autoAssignToSingleInput inside the click event handler was invoked
an async call stack which was resolved before the next button click handler completed.
As a result a pop up was showing up saying "The application is no longer modifying a new profile".

This commits fixes this issue by explicitly preventing this event lister handler been executed
in this case.
