Subject: [PATCH] fix(telescope.state.get_existing_prompts): it should only
 return keys that are numbers (#2684)

* fix(telescope.state.get_existing_prompts): it should only return keys that are numbers

* Table keys not table values should be numbers

* Rename get_existing_prompts to get_existing_prompt_bufnrs and make the impl more efficient
