Thanks for making this PR @davx1992 !
What a tricky issue, this makes sense theoretically, and worst case I don't believe it can do any harm?

@Salakar this is good one - there is linked commentary but the essential idea is: dispatch_after won't run if app is live but in background, but starting up this background task thaws the queue. Solves the symptom of FCM events delayed and only pasting when backgrounded app goes foreground.

Saw this on the issue earlier and it was a 'doh' moment for me, we should have had this in originally but I completely forgot about it when rewriting messaging 🙈 so LGTM.
