[Doctrine] Add support of autocompletion for the 3rd argument of "from" method

[Koc]

Hi!

Currently there is no autocompletion of the 3rd argument.

$qb->from('MetalCategoriesBundle:MenuItemClosure', 'mic', 'mic.id');

NB! this method supports only primitive types.

just used same completion as all user querybuilder parameters. "primitive types": dont wanne implement another filter. up to the user to get find the right one. :)
