Subject: [PATCH] Remove unnecessary if statement in scheduler (#10446)

# Objective

There is an if statement checking if a node is present in a graph
moments after it explicitly being added.
Unless the edge function has super weird side effects and the tests
don't pass, this is unnecessary.

## Solution

Removed it
