The following situation can occur: a computed field depends on one2many
lines, and during an onchange, a line is modified. Both the main record
and the line are new records. If the many2one field is not in cache on
the line, its value is fetched from the line's origin, and the field
will be triggered for recomputation on the main record's origin instead
of the record itself.
The fix enforces the following property: if new records are modified,
only new records can be triggered for recomputation.
