Removed 'Type' suffix from the generated test class

It's not a big deal but,

the suffix 'Type' was removed from form_type_name in this commit: https://github.com/sensiolabs/SensioGeneratorBundle/commit/29601b4293df3b3638d5d3e196854305a24336c3

But was not replicated to DoctrineCrudGenerator that generates a testclass like:

$form = $crawler->selectButton('Create')->form(array(
            'acme_acmebundle_formnameType[field_name]'  => 'Test',
            // ... other fields to fill
        ));
