Title: Correction for the test to work when hashCode == 0

Better correction to #45.
The c._inc() function start at 0. the result of toString is then used instead of the hashCode but then :

On a Variable the toString is build using the current value, when the internal value change it's keyCode value change. Trying to fetch a stored Variable after a change of value will then fail (For example when doing solver.suggestValue)
