[FIX] crm: reset auto probability if auto probability could not be computed

Or, in other words, set auto probability to 0 if no statistics yet.

Before this commit, if the automated probability could not be computed,
the automated_probability field on crm.lead was not modified.
That led to having leads stuck at 100% once won, even if going back to another
stage.
This happened only :
  - in an empty DB (no demo data) or
  - in a DB where the PLS cron had never ran and the PLS threshold was
    inactivated (=0).
Because, if the frequency table has never been built, we cannot compute the
automated probability.

After this commit, if the automated probability cannot be computed, we set
it by default to 0. If the probability and the automated probability was
aligned, probability is also set to 0.

Note: this could be an issue if both probabilities were aligned, then
someone deactivate the PLS cron and set the threshold to 0 (if not yet the
case), and clear the frequency table. (unlikely to happen but still..)
When updating updating a lead, we would lose the probability
-> auto proba set to 0 + proba set to 0 as they were aligned.
