Use 'ugettext' instead of 'ugettext_lazy' in 'cmsplugin_contact.nospam.widgets.HoneypotWidget.render()'

When rendering 'HoneypotWidget' language is already active and it is not necessary to use 'ugettext_lazy' as it returns object instance. Plus, string operator '%' will insert into string value of 'repr()' instead translated text. It results in incorrect HTML.
