Many tests are not producing expected SQL, tracked remaining ones with relevant issues.

Resolves #15994

{
using (var ctx = CreateContext())
{
var query = ctx.Entities1.OrderBy(e => e.Id).Select(e => e.NullableStringA.IndexOf("oo")).ToList();

we don't have "real" assert infra for null semantics tests. Will add it at some point

Wouldn't MayBe pattern for client solve the purpose?

the AssertQuery we use in this suite is different than what we use everywhere else - it doesnt support custom projections (always assumes we return IQueryable<NullSemanticsEntityBase>) This was added because we need to pass useRelationalNulls flag to dbcontext, which the normal assert query doesnt provide. However, vast majority of tests uses the c# null semantics so we can just switch to the infra we already have, and places where we would pass useRelationalNulls: true, we can test using CreateContext directly. But I would prefer to do this in a different PR
