App 2.40.1: an update always reaches the installer screen

Browse Source 
The car refuses the installer session, and only a refusal thrown at
once opened the installer screen; one that came back through the
session's result ended in a toast, so the update downloaded and then
nothing seemed to happen. Now any result but success or the driver's
cancel opens the installer screen with the verified APK, as does a
confirmation that cannot be shown, and a session silent for 20 s is
abandoned for it.
