Merge a09805236a54a8d4f4540b940b5d0c7e9c6c74d1 into 313f5392ef82db1e2dd81da8ccc9df52c2c4610d

Fix type mismatch in retainAll() calls that cause updateGroup --admin
and --remove-member to silently do nothing.

retainAll() compared Set<RecipientId> against Collection<GroupMemberInfo>,
which always evaluates to false (different types), emptying the set.

Replace group.getMembers() with group.getMemberRecipientIds() in all
three affected locations.

Fixes: updateGroup --admin silently failing to promote members
Fixes: updateGroup --remove-member silently failing to remove members
