[BUGFIX] Extbase: Don't use ORDER BY with COUNT(*) SQL statements

Databases that adhere to the SQL92 standard and enforce having all
columns that are using in any part of the query be part of the
SELECT/COUNT field list will throw an error when using COUNT(*) in
combination with ORDER BY.
Since ordering has no influence on the result of COUNT(*) the
ORDER BY query part has been disabled in getObjectCountByQuery().
