Wrong error message shown when set to an unsupported network

[edmundedgar]

If I visit
https://governor.kleros.io/
...in Brave with a custom RPC set to XDai (network 100), I expect it to say something like "wrong network", but in fact is shows me "Web3 not found"

The error message in the console triggering this is
VM14 8.94d5de1e.chunk.js:1 Contract KlerosGovernor not found on network ID: 100

It's not too bad because the advice is still correct, namely, "Please make sure you have your wallet unlocked on Mainnet or Kovan" but it confused me until I looked at the error in the console.
