Fix to #34728 - Split query with AsNoTrackingWithIdentityResolution()…

… throws ArgumentOutOfRangeException (#34742)

This is a regression introduced in 9.0 when trying to address a different regression (#33073)

Error is caused by a bug in JsonCorrectOrderOfEntitiesForChangeTrackerValidator, specifically it uses the initial SelectExpression to analyze structure of various shaper expressions in the query. Problem is that RelationalSplitCollectionShaperExpression has its own SelectExpression that described the collection - we should use that select expression rather than the parent.
Fix is to update SelectExpression used to process the expression when are processing RelationalSplitCollectionShaperExpression

Fixes #34728
