Missing IGMP V2 leave message when no group member is present
Issue
When an IGMP V2 group has more than one member/client, it can happen that no IGMP V2 leave msg can be seen but the IGMP V2 group has no members/clients anymore.
So it means that the group has no members already, but the IGMP V2 leave msg has not been sent by any of them before leaving the IGMP V2 group.
