Fix variant selection in emoji chooser

[Jeremy Bícha]

Impact
======
The variant selector in the emoji chooser was broken and will crash the app if used.

Test Case
=========
In an app like gedit, right click in the text area and select Insert Emoji
Look for one of the "people" emoji.
Right-click (or long-click) on the emoji and select one of the skin tones instead of the default yellow.
The emoji with the skin tone you selected should be added to the text area.

Regression Potential
====================
This fix was included in the gtk 3.24.2 release. There is a standing microrelease exception for GNOME point releases.

GTK 3.24 was a big enough release (with some bumped dependencies) that it's not very practical to push to Ubuntu 18.04 LTS so we selectively cherry-pick fixes there.

Other Info
==========
This bug is fixed in gtk 3.24.2. Its SRU for cosmic is being tracked in LP: #1808233

[Brian Murray (brian-murray)]

Why is the cosmic task open here? I don't see an upload in the cosmic queue and the description leads me to believe this may already be fixed there.

[Jeremy Bícha (jbicha)]

Brian, I have now added a note to the bug description to explain that the cosmic fix is being handled as part of the gtk 3.24.2 SRU. I did upload this fix for cosmic but I got Steve to reject it for me since we are doing to do the 3.24.2 SRU instead. I still haven't uploaded 3.24.2 to cosmic since I expect a 3.24.3 release "soon".

If you want to accept the bionic fix, I'll wait to verify the fix until after this issue is also fixed is in cosmic-proopsed. Or we can just wait a bit longer for bionic too.
