Avatars are not loaded when restoring from backup

[denilsonsa]

How to reproduce:

1. On phone 1, follow a few streamers and follow a few games. All locally, without signing in.
2. Go to Settings, scroll down to "Backup settings and data".
3. Somehow, copy those two files to another phone. https://pairdrop.net/ can come handy.
   • Alternatively, doing a full "Clear data" should also be enough to reproduce this bug.
4. On phone 2, on a brand-new Xtra install, go to Settings and scroll down to "Restore settings and data".
   • Since there are two files, we have to repeat this step twice, once for each file.
5. Go back to the main screen, and navigate to "Following".
6. Look at both "Games" and "Channels" tabs.

BUG: All the games and channels are listed correctly, but without any avatar picture.

Expected behavior: Once the app doesn't find the avatar picture, it can try downloading it from the server. In fact, it can already do that on the "Live" tab, but not elsewhere.
