Initialize horizontal panel as GONE and add logs

The horizontal layout view should only be visible when the configuration
has changed to landscape, so it should be initialized as GONE normally.
Also add more logs to help debug if/when this layout changes.

Bug: 198319256
Test: manual, verify correct behavior when rotating
