Subject: Change SimianGroupsServicesConnectorModule.GetAgentGroupMembership()
 so that it returns null if the user isn't a member of the group.

This matches the behaviour of the same method for Flotsam Groups.  This is the behaviour assumed by existing code.
Method doc also added to IGroupsServicesConnector to the make the contract clear.
