Fix indeterminate event order in character integration test
Fix indeterminate event order in character integration test

This fixes an issue where events were being received in a
different order than we were expecting during the running
of the character delegate lifecycle integration test.
Specifically, we were expecting the event corresponding to
the proxy server sending a SET_ENTITY_TYPE message to the
game to occur before the game raised a MULTIPLEXER_CREATED
event when spawning a multiplexer to handle the inbound
socket connection. This patch adds a slight delay to the
socket handler so that the multiplexer is not created
immediately. This gives the SET_ENTITY_TYPE message time
to fire successfully.
