The 'height' field was added in https://github.com/spesmilo/electrum/commit/cdfaaa260942b807f809c2c0414fb242a03e945a
At the time we thought we could just add it with a default value without a db upgrade;
however the issue is that if old code tries to open a new db, it will fail (due to unexpected new field).
Hence it is better to do an explicit conversion where old code *knows* it cannot open the new db.
