 This is fallout from fixing #5368 in PS. Now that we correctly get buddy-
 moved when somebody joins an activity, the following happens: The first
 buddy to join has their icon moved next to the activity. The subsequent
 buddies to join have their icons disappear completely from mesh view, but
 do reappear if they switch or leave that activity.

 Alternatively, if you start a sugar instance and three people are already
 in the activity, you see those three, but any additional buddies to join
 have the above behaviour.

 The problem seems to be that in SnowflakeLayout the buddy spacing code is
 in do_allocate and that isn't called on subsequent buddies being added.

 This needs to be fixed before pushing #5368 (in PS in Joyride) to Update.1
 otherwise it seems more broken than before...
