This patch fixes getDirectRoomMember not respecting direct rooms
with more than two members total but only two active. This commonly
occurs when users migrate to a new account by adding a new account
to rooms and leaving with the old one.
Other parts of the codebase (such as the people room list filter)
already respect the active member count of a room instead of the
total (historic) number of unique members.
This fixes the room details screen not showing up correctly, for
example missing the avatar cluster.
