[ADDED] Report Encoding exceptions during unary calls

[Rkiouak]

• As part of the client protojure funcitonality, exception propagation of encoding issues has typically not been done, and instead the caller has been responsible on validating their input. This PR adds exception logging and propagation on an encoding issue for unary calls only BUT note this will not prevent the unary call from being sent with an empty payload. However, since this invocation with an empty payload is existing funcitonality, this commit is made to improve debuggability and exception propagation.
