      With sharded collections, the index that the shard key is dependent on can be dropped, this prevents moveChunk() from working on the collection.

      Steps to reproduce:
      1. Start with an already sharded collection.
      2. Drop the shard key from the indexes.
      3. Attempt to run moveChunk(). This should fail with "errmsg" : "can't find index in storeCurrentLocs :: caused by :: "
