Bug description

The icon for the "Signal update", "A new version of Signal is available" notification is the same as the normal icon for when receiving a new message. This means that when glancing at the notification bar when an update is available, I think I have a new message, which is annoying!

I think the icon should look different, maybe the normal Signal icon with an upwards-pointing arrow in the bottom-right.
