[BUGFIX] Update tstamp on writeForeignField if any foreign value has changed. (IRRE)

This patch solves the problem where the timestamp in the column tstamp
was not updated when the sorting of the inline list (IRRE) would change.
It also updates the tstamp if one of the following fields change:
foreign_field, foreign_table_field, symmetric_field or one of the
foreign_match_fields.
