autotest: desktopui_ExitOnSupervisedUserCrash race fix

At the end of the desktopui_ExitOnSupervisedUserCrash, I was waiting
for a signal that the user session had ended while accidentally also
causing the UI to get torn down. This resulted in an unclean UI shutdown
that never sent the signal I wanted to see, so the test failed with
a timeout exception.

This change moves the listening for the session termination signal
so we properly wait for it before tearing down the UI.
