Add superclass initialisation for three Bot scripts

Three scripts didnt call their superclass Bot's __init__.
Logic was recently added to the Bot class which depended on
the object being initialised properly.

Added a plain super call to replace.py and solve_disambiguation.py
and revise states_redirect.py soas it uses the new Bot 'site'
property manager.
