Fixes#1825 by removing the check in the gateway_balances RPC handler
that returns the RpcInvalidHotWallet error code if one of the addresses
supplied in the request's `hotwallet` array does not have a trustline
with the `account` from the request.
As stated in the original ticket, this change fixes a discrepancy in
behavior between Clio and rippled, as rippled does not check for
trustline existence when handling gateway_balances RPCs

checks range doesn't exist
