[FrameworkBundle][Console] Load command from DIC after command from bundles.

It's better to load a command from DIC after other one. Because it allow easy
override of default (symfony/assetic/doctrine) command. The end user could do:

    # config.yml
   services:
       assetic.command.dump:
           class: SensioLabs\Shim\Assetic\DumpCommand
           tags:
               - { name: console.command }
