    authPrompt: Unset preemptiveAnswer on reset
    
    When we get a reset signal the preemptiveAnswer should be also unset or it will
    be used next time the user authPrompt will be activated, even without any further
    user interaction.
    
    Fixes #311
    
    
    (cherry picked from commit d21657fe61f9a41734554811c29c54979ca2dbb9)
