[IMP] crm : set automated_probability = 100 when stage won

If the stage is set to won, automated probability should = 100%
Without forcing it, it should be the case as all lead at stage won
have been won. (thanks Captain Obvious!)

But if a user mark as lost a lead that is at won stage, it will reduce the
probability of the won stage.

Also, if the cron didn't run recently, it could be that the autmomated probability
will give the same result than in previous stage (if no lead have been won at all).
