Fix TailorDev Watson uuids in frames

fix_watson_uuids.py

#!/usr/bin/env python3
"""
Use this script if you have corrupted frames in your watson history. In my
case, almost 400 frames had short ids instead of 32 chars uuids.

Usage:

$ cd path/to/watson/dir
$ wget GIST_URL -O fix_watson_uuids.py
$ python3 fix_watson_uuids.py
$ cp frames frames.bkp
$ mv frames.fix frames
