Subject: [PATCH] Hide network icons that have no asset

The rail dropdown renders /networks/<network>.svg for every entry with
no error handling, and three of the eight networks in crypto.ts have no
file: ethereum, plasma and tron. Those rows currently show a broken
image beside the network name. USDT has had three of them for a while;
adding Ethereum to USDC in #792 put the first one on a dropdown that
had been clean.

Hiding on error rather than adding artwork, because an Ethereum or Tron
mark is brand material and an invented one that doesn't match the
existing set is worse than a gap. The assets are still worth adding.

visibility rather than display, so the 20x20 slot is preserved and the
network names stay aligned down the list.
