PHPUnit with Forms about symblog-docs

[makusu]

@jaimesuez I faced the same issue a few minutes ago and I kept wondering why.

It seems like we can just change it into this.

    $form['contact[name]']       = 'name';
    $form['contact[email]']      = '[email protected]';
    $form['contact[subject]']    = 'Subject';
    $form['contact[body]']       = 'The comment body must be at least 50 characters long as there is a validation constrain on the Enquiry entity';

In my case, it works just fine after I changed it. I'm not sure if there's something that we should do (or missing) to make the original code working.

@dsyph3r any idea?
