Band Lineup 1.12.0: Sync keeps your moves and puts each person in one spot

Two Sync problems found by checking the real October 25 plan against the
board:

- Someone on the plan twice (Mike Powell is Leader and Guitar [Acoustic])
  could fill two spots, pushing a real player off the board. Which spot
  the duplicate took depended on the order Planning Center returned
  people, so it only happened some weeks. Assignment now uses each person
  once.
- Moving a synced person to another spot was undone by the next Sync,
  which re-placed everyone it had filled. A move is now a hand placement
  for the current plan and Sync leaves it alone.
