Update tempus data when updating deployments

Issue:
Currently, when a new version of tempus is deployed, the data of the old deployment is retained. This is an issue when new data should be created by the new deployment.

Specifically, a recent upgrade included new system widgets that were not persisted during the updating process, making the resulting deployment appear to not have the upgraded widget. The widget could still be created manually in the widget editor.

Expected Behavior:
When a new version of tempus is deployed, the data from the previous deployment should be merged with any new data (like widget bundle information).
