Don't log SQLITE_SCHEMA errors.

These errors are usually transient.  SQLite automatically retries
queries up to 5 times before actually reporting an error to the
application.  We expect SQLITE_SCHEMA errors to occur occasionally
due to the prepared statement cache, and it is ok.

If SQLite fails to automatically resolve a schema error, then
a SQLiteException will be thrown as usual.
