Description: 

The order customer does not "own" the entity in the classical Drupal sense, can't modify and delete it at any time after it has been placed. To clarify this, OrderInterface no longer extends EntityOwnerInterface.

Replaced methods:
1) getOwner() is now getCustomer()
2) setOwner($account) is now setCustomer($account)
1) getOwnerId() is now getCustomerId()
2) setOwnerId($uid) is now setCustomerId($uid)
