Title:  Remove worker's command frame before forwarding.

As per the spec, there is no actual command frame communicated between the broker and client.

**MDP/Client**

A **REPLY** command consists of a multipart message of 4 or more frames, formatted on the wire as follows:

* Frame 0: Empty (zero bytes, invisible to REQ application)
* Frame 1: "MDPC01" (six bytes, representing MDP/Client v0.1)
* Frame 2: Service name (printable string)
* Frames 3+: Reply body (opaque binary)
