[Crash] fb:// image crash after rejoining RM server

[FoolHen]

@kiwidoggie looked into this crash and found out its related to fb:// images.

[09:55] kiwidog: it's crashing on the texture loading code somewhere
[09:56] kiwidog: says canceling request 4 times
[09:56] kiwidog: fb://

So I tried disabling all uses of those images and it fixed the crash.
To repro you need a RM server on features/round-reset branch. You need to join with 2 clients, and with the second one you have to leave and then rejoin the server. Doesn't always crash, so you might have to rejoin more than once. Probably easier to tell me to set up the server and I'll join with my client, so you don't need to join with 2.
