Use currently selected data source when no source attached to saved query

[amsiglan]

Description

Opening a saved query that has no dataset stored with it, resets the currently selected dataset in the picker which breaks the query experience since the user will need to reselect the dataset which will then reset the query.

This PR adds a check for this case and retains the currently selected dataset

Testing the changes

Tested using local setup

Added video showing:
