The failure is due to change ([Refactor device registration to use
protocol types and controller from common, Fixes AB#3512895 by
mchand_microsoft · Pull Request #138 ·
identity-authnz-teams/ad-accounts-for-android](https://github.com/identity-authnz-teams/ad-accounts-for-android/pull/138))
made in BrokerHost app as part of change done to create device
registration APIs in common.

In the change I changed showing no device registration records from "[]"
to "There are no device registration records."

UI automation expects "[]", hence the test failed.

Fixing it by updating UI test case step to verify the string "There are
no device registration records." instead of "[]". This is better than
reverting to "[]", given the message is more friendly for manual testing
