6572: Close #6456: Allow empty body in AutoPush messages. r=rocketsroger a=jonalmeida

Allows nullable messages to be delivered to all observers. This was partly handled from the consumer-facing public API, but nullable messages were dropped when they were received from the push services.

6598: [ci skip] Bug 1620585 - reduce frequency for building snapshots r=pocmo a=MihaiTabara

We've added reproducible nightlies in https://bugzilla.mozilla.org/show_bug.cgi?id=1615248

 to be published under nightly.maven.mozilla.org/. As far as I understood, all the major projects have switched to using them instead of snapshots. Time to retire the latter then. 

First let's start with reducing the frequency from 10 times a week to three times a week and see if there are any downstream consumers that we don't know of that might have oversight. If nobody complains, I'll remove them completely in a week from now on.

6432: Do not pause or display media notification when all media is muted. r=pocmo a=everett1992

Firefox preview will display a notification and request audio focus even
when the playing media is a muted gif, webm or other 'lite' media.

My goal is to stop requesting audio focus when the media is not playing
audio.
 - I only considered muted media. I ignored media with volume == 0.0,
 and media with audioTrackCount == 0. I'm not _sure_ that
 audioTrackCount 0 means the media is not playing sound. A similar
 commit could track and check those values.
 - I added the check for muted audio in MediaAggregateUpdaterTest
 because I am nnoyed by the notifications firefox creates if I leave a
 page with a webm in an open tab. I think aggregating player state to
 NONE will disable the notification. People won't be able to play/pause
 muted media from a notification, but I don't expect that's a common
 usecase. The check can be moved to MediaStateDelegate to avoid chaning
 the notification behavior.

Fixes [mozilla-mobile/fenix # 6146](https://github.com/mozilla-mobile/fenix/issues/6146

)
