Disable notifications in live session

[cassidyjames]

Similar to but distinct from #62. We should disable all update notifications when running in the live session (and possibly in the guest session as @Philip-Scott mentioned, though I'm less sure about that) since there's not really anything a user can do.

Downstream issue: pop-os#49

Possible duplication of elementary/os#11 ?

[cassidyjames]

Ah yeah possibly. Though does the daemon start when the GUI starts anyway, or are they totally separate?

[donadigo]

The daemon and GUI are the same process, the daemon starts at the session startup, and when you launch AppCenter, it gets invoked without any arguments to show the window.

[cassidyjames]

@donadigo so even if we disable the daemon from starting in the live session, as soon as someone opens AppCenter once, they'd get notifications for updates?

[meisenzahl]

#1963 prevents an update of the cache. Therefore, the issue should then probably no longer occur.

Gonna close since it sounds like this was fixed
