Graph.find/2 not passing correct value to callback according to docs.

[vacarsu]

Steps to reproduce

Simply call the function as below:

Graph.find(graph, fn prim ->
  IO.inspect(prim) # <-- logs the primitive id instead of the full primitive
  true
end)

Expected Behavior

The docs state that the function should return the full primitive to the callback.

Actual Behavior

The value being passed to the callback is only the primitive's id.
