When browsing flatpak available apps in a fresh Aeon install, many of the icons
are not displaying. 

Reproducible: Always

Steps to Reproduce:
1.Open Flatpak
2.(Optionally) Click on any of the app categories, eg: "Play"
Actual Results:  
Most of the icons for software packages are not displayed. There is a gray
square where the icons should be.

Expected Results:  
All package icons are dispayed

Happens with a brand new Aeon install. Have not seen behavior running flatpak
on other distros. If I click on an app to view its details, the icon and
preview images on the page will load. (An odd exception to this rule is "Battle
For Wesnoth" for which the screenshots on the app's page don't load either.) 

If I run journalctl, I see the following two errors which may/may not be
related:
- gnome-software[4431]: Result of screenshot downloading attempt with status
code '404': Not Found
