The global layout related changes were wrong for T1 where debuglink
behavior is significantly different; in particular, it is not always
possible to communicate over debuglink.
This change reverts to the old behavior for T1B1 and keeps the new one
only for core-based models.
Asserting the device comes back to Homescreen, so the UI result is always the same
(when it does not get there, the assert will fail and the test will rerun).
