Fixed normal bug EXT-6660 (Just logged on resident is displayed as connected to group voice chat in the VCP)

Reason.
 VCP floater stores voice states of its participants. If invited in group voice chat avatar goes offline and then online LLAvatarListItem representing it will display it as JOINED.

Fix: added force setting of voice state in VCP for added participants.
