Additionally, set the new value and get the old one in one ini_set() call.

Fix PSR2 rules : "As per PSR2, the static declaration should come after the visibility declaration."

Without using ``--list|-l`` you get a too many arguments error.

As an example ...

```
[ 15/02/2016 17:45:32 ] [ C:\wamp\www ] >vendor\bin\doctrine-dbal d:re mysql57 mysql


  [Symfony\Component\Console\Exception\RuntimeException]
  Too many arguments.


dbal:reserved-words [-l|--list [LIST]]


[ 15/02/2016 17:47:39 ] [ C:\wamp\www ] >vendor\bin\doctrine-dbal d:re -l mysql57 mysql


  [Symfony\Component\Console\Exception\RuntimeException]
  Too many arguments.
