[Bug] CloudWatch Dashboard widgets need to be re-saved

[zackproser]

Is this a new bug?

• I believe this is a new bug
• I have searched the existing issues, and I could not find an existing issue for this bug

Current Behavior

When the CloudWatch dashboard for the RefArch is created, it points at the correct sources (CloudWatch LogGroups for Pelican, Emu) and its JSON is well-formed.

However, for some reason, the charts won't load initially until you edit them and save them. Saving them - re-selecting the loggroups and leaving the widget code unchanged allows the charts to render.

Expected Behavior

The Dashboard widgets should render properly out of the box.

Steps To Reproduce

1. Deploy the RefArch
2. Visit the CloudWatch dashboard that the RefArch creates
