The 'predictive lead scoring' task (#1925439) changed the way stages are marked as 'won'. This introduced a bug in the 'Won' filter of the crm 'Activites' reporting view. This commit correctly applies the domain on the 'is_won' property of the crm.stage. Task #2009515 closes odoo/odoo#34087 Signed-off-by: Jérome Maes (jem) <jem@openerp.com>
