BootMultiSWIAgent never dies

[Adam Young]

I noticed a small bug causing the Boot agent to never die:

FIle: src/main/sarl/au/edu/rmit/agtgrp/agtcity/sarl/agents/dummy/BootMultiSWIAgents.sarl

ln 70: val agent_UUID = occurrence.agentIdentifiers
Should be:
ln 70: val agent_UUID = occurrence.agentIdentifiers.get(0)

Otherwise the UUID is never removed from the agentsToBeCompleted and the Boot agent never dies.
