Query: InMemory throws "nullable object must have a value" for queries projecting into anonymous type via optional navigation

[maumar]

query:

ss.Set<CogTag>()
    .GroupBy(t => new { t.Gear.HasSoulPatch, t.Gear.Squad.Name })
    .Select(g => new { g.Key.HasSoulPatch, Name = g.Key.Name.ToLower() })

when we translate key selector its in a form of [Microsoft.EntityFrameworkCore.Query.EntityShaperExpression].HasSoulPatch

EntityShaper gets converted to EntityProjectionExpression but we don't check if it was nullable - we should, and if so add null propagation to the member access

Also applies to nullable columns typed to non-nullable (inside predicate)
