FIX update status on create supplier order for trigger

• it's similar as PR Update ticket.class.php Bug-fix Issue #31206 #31208
• the status is not set in the trigger and if the external module can do an update of the object and the status is set to NULL in database

Remarks

• dol_clone() function uses "2" as second argument to keep the same code for upper versions of Dolibarr
  Should I backport the full function in Dolibarr v14 ?

• status attribute is used in commonobject

• statut attribute is used in this supplier order object (see update method)

When error is in travis at the very begin of process,you can try to restart travis. If you don't have permission on restart button for travis, it can be doneby repushing i think.
