ZF2013-03: Pdo\Connection getResource -> missing connect()

Hello,

through the fix related to: http://framework.zend.com/security/advisory/ZF2013-03

Always the trigger_error get's raised in Adapter/Platform/Mysql::quoteValue

Now Pdo\Connection get's connected when getting the resource.
Like in Mysql\Conneciton already done.

Maybe the other Driver are also affected....
