On load callback never gets triggered for dashboards with QuickSightConsole instead of Dashboard

[alexgurr]

The onload call back works correctly with URLs that are specific dashboard URLs, but when the URL is generated with an API payload (server side) with this:

QuickSightConsole: {
	InitialPath: '/start/dashboards'
}

instead of

Dashboard: {
	InitialDashboardId: 'dashboard id'
}

the client side SDK will never call the callback.
