[Insight] Symfony controller action method should not be too long

[hackzilla]

15% of all actions have more than 20 lines. This violation is raised when more than 10% actions are too long.

• 21 lines for TicketController::replyAction() in Controller/TicketController.php, line 154

We could do this in all actions:

if (!$ticket = $ticketManager->getTicketById($ticketId)) { throw .....; }

as much as I'm tempted, the Coding Style will moan.

I was thinking separate Controllers for each bit.
It's been something I've been trying to fix for a while.
