Using `@YawnProjection` picks up non-constructor data class `val`

[Nava2]

Example data class:

@YawnProjection 
data class Foo(
  val bar: Long,
) { 
  val baz: String = bar.toString()
}

The generated projection class is:

object FooProjection : YawnProjectionRef<Foo, FooProjectionDef<Foo>> {
  public fun <SOURCE : Any> create(
    baz: YawnQueryProjection<SOURCE, String>,
    bar: YawnQueryProjection<SOURCE, Long>,
  )
// ...

Expected projection:

object FooProjection : YawnProjectionRef<Foo, FooProjectionDef<Foo>> {
  public fun <SOURCE : Any> create(
    bar: YawnQueryProjection<SOURCE, Long>,
  )
// ...

computed properties are ignored as they are computed and not provided.

good catch - I literally ran into a similar issue yesterday trying to use reflection to support value classes (need to figure out fields by the constructor instead of members)
