deflakey: TestCompactionHash in integration

We should use WithCompactPhysical to wait for compaction to finish,
because 50ms sleep can't guarantee compaction is done.

Based on the log, the defragment is finished before compaction, which is
not expected. This patch is to make sure compaction should be finished
before assertation.

```
