Fix SNICKER client-daemon setup

This commit fixes two minor bugs encountered in
running create-snicker-proposal.py. First, the
port for AMP connections was not correct (by
convention it is now the Joinmarket proto main port
minus 1000), second in the above mentioned script,
the reactor startup client side was not disabling
the Joinmarket protocol, as it should.
