Update gnome-desktop3 to 3.30.2

[Jeremy Bícha]

Impact
======
This updates the GNOME version number reported in Settings > Details > About to 3.30.2

This is the final scheduled point release for GNOME 3.30.

I'm also cherry-picking a potential crash bug fix from the gnome-3-30 branch since there might not be another 3.30 release tarball.

This also includes the fix for LP: #1807127

Test Case
=========
From Ubuntu 18.10, open the Settings app.
Navigate to Details > About
The GNOME version number should say 3.30.2

Regression Potential
====================
There is a micro-release exception for GNOME:
