Issue 175 test group deletion new workflow

This is done! Please review and let me know if there needs to be any changes.
What happens if this isn't here? You're not really using it. In line 82, if you wanted to use it, it should be header.click_groups_profile_menu_item() rather than home_page.header.click_groups_profile_menu_item(). Let me know if I am not understanding this correctly.
