Greeter won't unlock when app raised by url dispatcher is already focused

[Alan Pope 🍺🐧🐱 🦄]

I have tried this on #294 and #250 after clean boot.

Send the device a text message
Tap notification
Expect messaging app to be opened (if closed) or raised (if already opened).

On both #250 and #294 it's been unreliable at doing this. Usually if messaging-app was not open it will be opened. However generally if the app is already open then tapping the notification will not raise the app.

On #294 sometimes the OSK will just appear over the top of the welcome screen.
On #250 it generally just does nothing.

This happens irrespective whether the device was locked and sleeping or at the welcome screen awake.

FWIW, it never worked when the app was already running (there simply isn't code that would deal with that).

I've been trying here and at least with "upstart-app-launch dialer-app" I've seen a 100% reliable focusing of the app, so as long as the backend (telepathy-ofono?) kicks the messaging app to start, I don't see anything wrong with how it works now.

Investigating further.

You can replicate what the telephony backend does with:

$ url-dispatcher message:///123

Where 123 is a phone number. I've been able to replicate the "keyboard over greeter" behaviour when the messaging app was already launched and having executed the above.

In general, there's nothing new here or unforeseen behaviour that I can find.

[Michał Sawicz (saviq)]

Humpf, there seems to be code dealing with that after all... But indeed it doesn't work when the app was already focused.

I.e. steps to repro:

* launch messaging app
* lock the phone, press power to turn display on
* $ url-dispatcher message:///123
→ keyboard visible over greeter

Journey working correctly:
* launch messaging app
* swipe to dash or focus another app
* lock the phone, press power to turn display on
* $ url-dispatcher message:///123
