Bug in Members > Friends pagination

[SlothLoveChunk]

There seem to be a couple issues related to pagination on the Members > Friends tab.

1. If you're viewing an individual member's friends (e.g. /members/{username}/friends/) and click page 2, the list will update, but it will now ALL active members, not just your friends.

2. Now, while on the same page as above, if your logged in and change the "Order By" filter on the top right it will show YOUR friends. Again, it should be showing the member's friends.

Note, to recreate either of these there must be > than 20 friends in the list, otherwise the paging will not appear.
