dependencies not on graph disappear when editing

[MareoRaft]

A node lists its dependencies. When you go into edit mode for the node's dependencies, any of the dependencies that are not currently in the client's graph disappear.

This is an issue because people will be erasing valid dependencies by accident / slash won't be able to add new dependencies without erasing old.

To solve the issue, we should build some way to request info from the server without necessarily getting the entire nodes. Or I suppose it would be okay to get the entire nodes. All dependencies can theoretically exist in the clients "graph" but not necessarily in their "visible graph".

This should probably be a high priority to at least patch this for now.
