[FIX] crm: fix archive / restore PLS inconsistencies

SPECIFICATIONS

Fixes following issue: when a lead is marked as lost, the probability is
correctly set to 0 but not the automatic one. If one clicks on the "Set to
automatic", the probability is updated, which un-archives it without really
restoring it, meaning we get in a very strange state outside the expected flow
(no Won/Lost buttons, ...).

With this commit the automated probability is set to 0 when setting as lost.
Moreover restoring a lead recomputes its probabilities.
