relay.node on subtype needs initialization

[devkral]

Consider the code

@strawberry.type
class Sub:
  node: relay.Node =  relay.node()
  nodes: list[relay.Node] =  relay.node()

@strawberry.type
class Query:
  @strawberry.field
  @staticmethod
  def sub():
    return Sub

schema = Schema(query=Query)

This code should work but doesn't, it requires an initialization for node

Note there is a workaround (initialization with None or empty list, or (I think whatever))

...
  @strawberry.field
  @staticmethod
  def sub():
    return Sub(node=None, nodes=None)

there is a better workaround: just provide a default of None
