Temporal rewriter may have issue

Exception -
```
System.InvalidOperationException : An exception was thrown while attempting to evaluate the LINQ query parameter expression 'Convert(value(Microsoft.EntityFrameworkCore.Query.ComplexNavigationsCollectionsQueryTestBase`1+<>c__DisplayClass25_0[Microsoft.EntityFrameworkCore.Query.TemporalComplexNavigationsSharedTypeQuerySqlServerFixture]).ss.Set(), DbSet`1).TemporalAsOf(1/1/2010 12:00:00 AM)'. See the inner exception for more information.
---- System.InvalidCastException : Unable to cast object of type 'Microsoft.EntityFrameworkCore.Query.Internal.EntityQueryable`1[Microsoft.EntityFrameworkCore.TestModels.ComplexNavigationsModel.Level2]' to type 'Microsoft.EntityFrameworkCore.DbSet`1[Microsoft.EntityFrameworkCore.TestModels.ComplexNavigationsModel.Level2]'.

Query
```
DbSet()
.OrderBy(l1 => l1.Id)
.Select(l1 => new {
l1 = l1,
inner = <>c__DisplayClass25_0.ss.Set()
.Where(l2 => l2.Name != "Foo")
.Select(l2 => new {
l2 = l2,
innerL1s = <>c__DisplayClass25_0.ss.Set()
.Where(innerL1 => innerL1.OneToMany_Optional1
.Any(innerL2 => innerL2.Id == l2.Id))
.Select(innerL1 => innerL1.Name)
.AsEnumerable()
})
.Select(<>h__TransparentIdentifier0 => <>h__TransparentIdentifier0.innerL1s
.ToList())
.FirstOrDefault()
})
.Select(<>h__TransparentIdentifier0 => <>h__TransparentIdentifier0.inner
.ToList())
```
We are adding convert to DbSet in rewriter for test and it is throwing something off.

Only happens for STET so may be because Set is never db set.
