Remove unused variable from tests files

hi @Hardik_Patel_12

patch #2 LGTM + 1 RTBC

Thanks!

Thanks @Hardik_Patel_12 , @kishor_kolekar for the patch. here is one more unused variable in test files. I have removed in new patch, kindly review.

The patch from #5 applies good for me.
Also I think empty line should be removed before return $form;
in tests/modules/ctools_wizard_test/src/Form/ExampleConfigEntityGeneralForm.php
see below.

/**
   * {@inheritdoc}
   */
  public function buildForm(array $form, FormStateInterface $form_state) {
    // The label and id will be added by the EntityFormWizardBase.

    return $form;
  }

#5 Patch is no longer to apply

Updated correct screenshot.

BTW I have created new issues and fixed all Unused variable.
