Renaming a node does not update the jobs associated with the node.

Steps to reproduce:
1. Create a node,
2. Create a job and assign it to the node,
3. Rename the node

Bug: From the jobs perspective the node is no longer there. From the Nodes perspective there is no jobs.

Ideal solution: when rename the nodes, update all the jobs associated to point to the new name.

Justification: As part of the maintaining a lager cluster of nodes it becomes necessary to occasionally relabel some of the nodes to meet new lab naming conventions. Current this break makes it so I have to go in and fix a lot ~50 jobs per node.
