Guest user (embedded) doesn't get access to datasets used only in dashboard filters

[Vitor-Avila]

It's possible to grant dashboard access to a guest user (guest_token), by specifying the dashboard uuid in the guest_token resources. The operation grants access to all datasets used in charts added to the dashboard, however it doesn't grant access to datasets that are only used in dashboard native filters.

How to reproduce the bug

1. Create a chart using any dataset.
2. Save the chart and add it to a dashboard.
3. Create a virtual dataset for the same table (a select *... would be enough).
4. Create a dashboard filter using the virtual dataset.
5. Enable embedded access for the dashboard.
6. Create a guest_token and grant access to this dashboard.
7. Access this dashboard in embedded mode.

Expected results

The dashboard filter should load properly.

Actual results

A permission error is displayed in the filter.
