"Failed to cast" error with Remote.Cons

[TomasMikula]

The following test case (when added to PersistentExecutorSpec)

    testFlow("cons") {
      ZFlow(Remote(1))
        .map(Remote.Cons(Remote(Nil), _))
    } { result =>
      assertTrue(result == List(1))
    },

results in

Exception in thread "zio-fiber-28" zio.FiberFailure: Failed to evaluate remote: Failed to cast Primitive((),unit) to schema Sequence(Primitive(int,Chunk()), List)

If you explicitly give the type of Nil it works:

testFlow("cons") {
      ZFlow(Remote(1))
        .map(Remote.Cons(Remote[List[Int]](Nil), _))
    } { result =>
      assertTrue(result == List(1))
    },

without that the
implicit val nil: Schema[Nil.type] = singleton(Nil)
is picked up from zio-schema instead of a sequence of int schema.

I think this is a zio-schema issue similar to another I already fixed in it regarding Left and Right was not encoded the same way as an Either.
