Patching Evc's primary_links attribute returns an unrelated response code (500)

[ArturoQuintana]

The action to patch the Evc primary_links attribute returns a code error 500, forbidding modifying that attribute. See example:

    def test_150_patch_primary_links(self):

        api_url = KYTOS_API + '/mef_eline/v2/evc/'
