Dexter doesn't seem to consider DashStudio dashboards

[bhomrich]

Describe the bug
I know that DashStudio is beta, however, customers are starting to use the format.
It would be an improvement to have DashStudio dashboards subject to the same decomposition as legacy dashboards.

To Reproduce
Steps to reproduce the behavior:

1. Create a Dashkit based dashboard
2. Retrieve the data from the controller, requesting dashboard information.
   Confirm that the dashboard was not included.
