Revert "Revert "Test app for call companion app" am: 456dc761 am: d93cf54a am: a2594245"

This reverts commit 60599ffc.

Reason for revert: <aosp/1535284 causes build broken in aosp because DEVICE_PROFILE_WATCH is not in aosp and TH didn't find it, but no conflict in master; however, it was removed in master because the revert (aosp/1534575) in aosp automerges into master; we still need it in master>
