* NH-1747 FIX

* In all our test it happened only for NHibernate.Test.Legacy.MultiTableTest.MultiTableCollections
* The mapping Multi.hbm.xml had a column named "parent" to represent the Key of a set for the relation Lower->Top and SubMulti->SubMulti everything in the same hierarchy
* NH TODO: Have to add an early check of same ColumnName used to represent two relations.
