Fix audio_manager_unittest should update with AudioDevice display_name

In later patch of https://codereview.chromium.org/2079843003/, I update the code to display AudioDevice display_name. But I forget to update the unittest. Since try server is not running in USE_CRAS, it is not detected.

BUG=628342
TEST=run in USE_CRAS building condition, it returns to work fine.
