AssetIds migrated from AssetId (pre-v1.6.0) not displayed in panel query editor

[fridgepoet]

What happened:
While upgrading from a dashboard with Asset selected that is pre-v1.6.0 to v1.12.0, the Asset is no longer selected when opening the panel query editor.

v1.5.1:

v1.12.0 - note that Asset is now blank

One workaround seems to be to click the dropdown menu and select the Asset in v1.12.0 and save the dashboard.

What you expected to happen:
While upgrading from a dashboard with AssetId that is pre-v1.6.0, I expect the AssetId to still be selected in the Panel.

How to reproduce it (as minimally and precisely as possible):
Create a dashboard on a pre-v1.6.0 like SiteWise v1.5.1 and add a panel query where you have to choose an Asset, like Get Property Value History
Save the dashboard.
Upgrade SiteWise to a later version like v1.12.0.
Open the dashboard and panel. You should observe that Asset is no longer selected in the query editor.

Anything else we need to know?:
A single AssetId was migrated to AssetIds array in #153 and released in v1.6.0.
