[bugfix] Do not recreate a deleted page

- assign newtext only once outside the loop and use Page.save method
- assign global.async to the async parameter
- use nocreate=True to prevent recreating the page_empty_check
- leave the method without further action when recreating fails
  but show the default warnings
