This commit fixes an issue introduced by Qiskit#589 where in certain cases node holes in a graph would result in a panic being raised. This was caused by a logic bug in trying to recreate the holes. Additionally, there were several places where graph methods removed nodes that the flag to indicate there were removals would no be set. This commit fixes all of these issues so that deepcopy/pickle works as expected.
