GH11551 - fix OneToManyPersister::deleteEntityCollection when using

single-inheritence entity parent as targetEntity.

When using the parent entity for a single-inheritence table as the
targetEntity for a property, the discriminator value should be all
of the values in the discriminator map.
OneToManyPersister::deleteEntityCollection has been amended to
reflect this.
