fix(honeycombio_board) graph_settings should revert to false when removed

[jharley]

When removing a setting from graph_settings the value is not reverted to "false" (the documented default).

During testing #399 was discovered but I believe the fix there is to re-implement the resource in the Plugin Framework.

Initially reported via Honeycomb Support.
