rpc: use existing rpc logger for wtclientrpc
The logger string used to identify the wtclient and wtclientrpc loggers was the same, leading to being unable to modify the log level of the wtclient logger as it would be overwritten with the wtclientrpc's one. To simplify things, we decide to use the existing RPC logger for wtclientrpc.
