The decision to treat COMMIT/BEGIN as a "read" in isWriteQuery()
for the benefit of ChronologyProtector was first introduced
in r47360 (8653947b, 2009).
* Re-order strings in isTransactableQuery() to match the regular
expression in isWriteQuery() for quicker mental comparison
* Add missing visibility to DatabaseSqlite->isWriteQuery, matching
the parent class implementation.
