When dissecting any message containing a "transport layer address", if the
address was NULL (which is valid), the offset pointer was not incremented by 1
and the remaining fields would not be dissected correctly.

This occurs in the following types of messages:
CHANNEL_PARAMS, JOIN, SESSIONS

This occurs in all previous versions including the original ACN plug-in for v
0.99.4.
