[FIX] models: on update, call inverse function on field even when it is stored

The inverse function of a stored computed field was not called when creating or
writing on a record with such a field.

Note that this change triggers bugs if compute methods are used to determine
default values.  In particular, a related field usually defaults to a null
value, which is then set to the field with its inverse function by create().
This violates a non-null constraint if the related field is required.
Therefore, compute methods are no longer used to determine default values.
