Observer wallet address and farmer rewards

[ghost]

v1.3.1

Don't know if this is a bug, but I doubt it or someone would have noticed it sooner.

On the command line:
chia keys derive -f <fingerprint> wallet-address -i 0 -n 1

In the GUI, paste address into farmer and pool reward addresses and get message:

No private keys for one or both addresses. Safe only if you are sending rewards to another wallet.

However, using:
chia keys derive -f <fingerprint> wallet-address -i 0 -n 1 --non-observer-derivation
Creates no warning message.

Using the same fingerprint as the one logged in with (farmer key).
