dont allow queries to start when compact() just started

[staltz]

Problem

compacting is set to true only when compactionProgress reports something, but that could take a while (it needs to write a block in AAOL), and in the meantime, someone could call ssb.db.query, which can proceed if compacting === false.

Solution

As soon as we call compact(), set compacting to true.
