[MERGE] backport saas-1 rev 8728
[FIX] mail, project, project_issue, crm_lead: fixed 'XX Created' subtype not triggered because of condition
based on state=new and not state=draft.
For tasks, issues and leads, no generic 'Document created' message is posted anymore
because of the 'XX Created' message with subtype automatically logged.
Generic creation message is logged before automatic subscription to enable
message pushing to responsibles.
