Adapt TrackBestTrackCreator to automatic ToolHandle retrieval in gaudi/Gaudi!429
With gaudi/Gaudi!429 (merged), any ToolHandles declared by a component are automatically retrieved after initialise(). This breaks TrackBestTrackCreator in the case of Upgrade, because the TrackStateInitTool has not been ported to the Upgrade tracking.
This MR ensures that the Properties to disable tools continue to have the intended effect
