Unpublish then republish graph resets all resource map layer config

[CWDamm-Kint]

Tested in Arches 7.5 (Arches for HERs). Republishing the graph resets the styling for resource layers (set within the Map Layer Manager) to the defaults.

Some further notes after digging into this issue:

• This issue occurs in v7.6 as well as 7.5. It has not been tested in 8.0. Interestingly, it is also an issue back in 6.2.x - if you apply map stylings and then rename a node, the map stylings are reset.
• The styling reset occurs at unpublish (as this calls save).
• I see the following psql log statement when unpublishing, which looks to insert new stylings.

• The reason this error happens seems to be because the node.config doesn't seem to be updated in self.nodes in graph.py, so it is saving an old version (the original) of config. This seems to be, because when the map stylings are changed in Map Layer Manager, it isn't updating the stored config in graph.py.
