Revert of Removing unused audio device tests

Revert of Removing unused audio device tests (patchset #1 id:1 of https://codereview.webrtc.org/2716843002/ )

Reason for revert:
I unfortunately have to revert this since trybots are still trying to run these tests and now they fail because the tests aren't there :-/  Before relanding, can you work with engprod to make sure we don't run them?

A revert of this CL (patchset #1 id:1) has been created in
https://codereview.webrtc.org/2720173004/ by henrika@webrtc.org.

The reason for reverting is: The test should no longer be executed on any bot
and it is therefore safe to remove it again..
