Because the global variable g_PlayerAssignments was not updated until after the handlers were called, and because the handler in GameRegisterStanza.js was referring to the global variable when generating the iq stanza to send to the gamelist, this was causing the gamelist to be updated with the previous player assignments instead of the correct values.
This will pass a playerAssignments argument to both OnClientLeave and OnClientJoin handlers(/gui/gamesetup/) and use the argument instead of g_PlayerAssignments in the handler registered by GameRegisterStanza.js.

Test that when joining and leaving a match, the lobby gamelist is updated with the correct players that are inside the match.
