EAGLE-1337: Fixed bug when loading graphs with no graph configs

[james-strauss-uwa]

Fixed bug where code would try to set last graph config as active, even when no graph configs exist.

Now the code checks that at least one graph config exists. If none exist, then graph.activeGraphConfigId is set to undefined.

Reviewer's Guide by Sourcery

The PR fixes a bug in the graph loading logic by adding a check for empty graph configurations. When no graph configs exist, the code now explicitly sets the activeGraphConfigId to undefined instead of attempting to access a non-existent array element.

Updated class diagram for LogicalGraph

classDiagram
    class LogicalGraph {
        +activeGraphConfigId: GraphConfig.Id
        +graphConfigs(): GraphConfig[]
        +loadGraph(dataObject)
    }
    class GraphConfig {
        +getId(): Id
    }
    LogicalGraph --> GraphConfig
    note for LogicalGraph "Added check for empty graphConfigs array before setting activeGraphConfigId."
