Subject: [PATCH 007/124] Geary.Db: Update SQL logging

Ensure all code paths that execute SQL are logging it if enabled, and
clean up the log formatting.

Add new `enable_result_logging` static property to control result
logging separately from SQL logging, so we can get SQL logged without
having to see email. Clean up result formatting, and keep track of the
current result row number and log that as context.
