connectfour/controller: Prevent list access by negative indexing.

Browse source 
Currently, if a user does 'move 0', he moves to column 6(last column)
in connect_four which is unwanted behaviour and happening due to
list getting accessed through negative index (-1).

Added a check for that in controller.py file.

Fixes #343
