:fire: :bug: Don't pull on input nodes

[liamhuber]

A simple call invokes a pull, including pulling the parent tree -- this blows up when the loop is inside a parent scope instead of alone. Since we know these are just user input nodes with direct value connections to the loop macro's scope, we never need to run the pull, or indeed even a fetch the value.

Before, this caused trouble, now it's fine:

from pyiron_workflow import Workflow

@Workflow.wrap.as_macro_node()
def LoopInside(self, x, y):
    self.to_list = Workflow.create.transformer.inputs_to_list(
        3, y, y, y
    )
    self.loop = Workflow.create.for_node(
        Workflow.create.standard.Add,
        iter_on=("obj", "other",),
        obj=x,
        other=self.to_list
    )
    return self.loop

li = LoopInside([1, 2], 4)
li().loop
