[ASTERIXDB-2246][STO] Ensure Metadata Cache Updated on Rebalance

- user model changes: no
- storage format changes: no
- interface changes: no

Details:
- Ensure metadata cache is updated to the target
  dataset by commiting the transaction before
  downgrading the write lock. This prevents waiting
  readers from reading a stale cache that points
  to the source dataset that will be dropped.
