Sensitive information are logged

WHen experiencing #65 (closed) I've seen an issue related to #55 (closed)

CommunicationError: Problem occurred during communication with: url=http://127.0.0.1:36497, request={"id": 0, "jsonrpc": "2.0", "method": "beekeeper_api.create", "params": {"wallet_name": 
"Gandalf@Mainnet", "password": "CENSORED", "token": "1e53c453c2bf36283b752d073d29a85c0315cf4994d7777978e34e9e5cda2ad6"}},

not sure about tokens.
Potentially there could be some extra logging level to log in those messages for debug version.
