Fix SQL query to retrieve language setting
In commit e171f6f (Migrate all DB code to use PDO, 2012-08-08), PDOStatement::fetchAll() was introduced as a drop-in replacement for mysql_fetch_array(). However, PDOStatement::fetchAll() returns a list of all results while mysql_fetch_array() returns a single result only. Instead of adding the missing indirection, simplify the code by using PDO::fetchColumn(). Also add some safeguards to prevent warnings if the result set returned by the query is empty.
