This fixes an issue that occurs when marking fields to compute in the
following situation:
- it occurs before the actual modification,
- a relational field is marked to compute,
- the same field is traversed to inverse some dependency.
When the marking occurs after the modification, the traversal of the
field should actually recompute the field. However, if the marking
occurs before the modification, the inversion of dependencies must be
based on the current value of the field. This is the case with method
unlink(): we call method modified() to mark the fields that currently
depend on the records to be deleted, and the fields must be computed
only after the deletion!
