Update dependencies in composer.json

@spolischook You mean enforcing Symfony 2.7 in the deps? My fix doesn't change the minimal required version.

[spolischook]

it's add Symfony 2.7 support? Other parts is work good with 2.7?

[jbgomond]

Yes, this was the code triggering deprecated notices.

[althaus]

Other parts is work good with 2.7?

Yes, I haven't found any other issue yet.

Symfony 2.7 deprecates the setFactoryClass and setFactoryMethod methods in favor of a combined setFactory call:

@cystbear Yes, our fork runs fine with 2.7 in our dev environment. The fix isn't big magic.

:+1: Works for me, it is just replacing the old methods by the new ones ;)
