STORM-287 FIXED changing currnet outfit with an outfit dragged from Library to My Inventory->Current Outfit folder.

Crash happened when trying to create new group while other group was still updating. It was caused by invalid iterator mMemberProgress in LLPanelGroupGeneral::updateMembers().
Its usage shouldn't have been reached when member list is cleared and empty thanking to gdatap->isMemberDataComplete() check at the beginning of the function. But when the new group was created while members of other group were still updating this
protection failed: in LLGroupMgr::processGroupMembersReply() for the group being created mMemberDataComplete was set TRUE when group size was zero(because this new group still
had no members). So the check for completness in LLPanelGroupGeneral::updateMembers() was succesfully passed, and further in this method viewer crashed.

- Added check for emptiness of member list into LLPanelGroupGeneral::updateMembers().
