Handle case where body tag is not yet present

Occasionally, when calling is_text_present or is_text_not_present,
it will throw an exception because the body tag isn't present.

Assuming that this is because the page hasn't fully loaded yet,
handle this acception by simply iterating through the while loop
again.
