If graph has multiple branches, End command is enqueued on launch stream which
makes sure all the internal parallel streams are finsihed.
When node is removed from the graph, indegree and outdegree are not getting update correctly for parent, child nodes and
resulting in endNode not having deps on parallel commands. Resulting in graph sync issues.
