fix wallets loading on switch
Quick fix that avoids the wallet balance going into a loading state after every switch wallet.
Taking a deeper look, I actually think we need some sort of variation of this function there. I'd reevaluate the need to refresh the wallet data though which is called internally of that loadWallets function.
@walmat Did you find a case where it breaks? I tested a few different paths and they all seemed fine, so jw what case breaks?
The other wallet cleanup PR fixes this in a better way, but I thought this one is fine if that one takes longer than this release cycle to approve.
Going to just close this in favor of https://github.com/rainbow-me/rainbow/pull/6642
