Subject of the issue

Application page failed to load if app state value not set

Your environment

Only verified on Chrome but very certain that it will happen on any browser

Steps to reproduce

1. In app lap, create a application interface using ARC56. This app spec must have a configuration for global storage key with key value type is address
2. Deploy the app (if need to)
3. Init the global state but don't set any value. This is valid

Expected behaviour

The application page should load. It should show empty value for the global state.

Actual behaviour

The application page crashes because it attempts to decode empty byte array to address.
