The "_method" requirement of route "fw_contact_index" is deprecated in symfony 2.7

[skonsoft]

Hello,

After migrate to Symfony 2.7, i got this notice:

DEPRECATED - The "_method" requirement of route "fw_contact_index" in file

"/var/www/dev/project/vendor/frequence-web/contact-bundle/FrequenceWeb/Bundle/ContactBundle/Resources/config/routing.xml" is deprecated since version 2.2 and will be removed in 3.0. Use the "methods" attribute instead. 

Can you fix this.
