[IMP] stock: Activity schedule from stock orderpoints

When an orderpoint triggers a procurement for a product and the system does not find the procurement route, it schedules an activity remembering what was the error.

If a normal user without admin access rights, makes an action that triggers the orderpoints, like confirming a MO, the activity schedule is not creating due to an access error on 'write' operation to a Product Template.

So, all activity schedules triggered from an orderpoint should be created without checking access rights.
