fac1dd9dff test: Fix authproxy named args debug logging (MarcoFalke)
Pull request description:
In Python the meaning of `args or argsn` is that `argsn` is fully ignored when `args` is a list with at least one element. However, the RPC server accepts mixed positional and named args in the same RPC.
Fix the debug log by always printing both. Also, add a new `_json_dumps` helper to avoid bloated code.
Can be tested via `--tracerpc` on a call that uses named args mixed with positional args.
