Public bug reported:

When a trusted prompt session is open on top of the dash, and the screen
is blanked (either via timeout or pressing the power button to turn it
off), the app which is running in the prompt session disappears upon
turning the screen back on. In some cases, this leaves the dash in a
state where the user is unable to interact with it, and the only
recourse is to reboot or run "restart unity8-dash" if the Terminal or an
adb shell are available. In some cases, this also leaves the app which
was in the trusted prompt session, running in the background, and it
will not get terminated by the system.

To reproduce:

1: Go to the YouTube scope.
2: Scroll to the bottom of the results and tap the "Log-in to YouTube" result entry.
3: When the online-accounts-ui opens up, turn the screen off.
4: Turn the screen back on and notice the login window for YouTube is gone, and the dash cannot be interacted with.

So far, I've only been able to do this in the dash, either with the
YouTube log-in, or with the app purchasing flow (which is slightly more
complex to test).

When reproducing this in ubuntu-system-settings-online-accounts, the new
account login window goes away, but it is still possible to interact
with the system-settings UI, so the user can recover by trying to add
the account again, or just quitting system settings.
