Minor change was required in one of the tests in modules_unittests after another
modification referenced
in the title.

On iOS, playout and recording sides share one and the same audio unit and we now
make that more clear
by using a common state for iOS (not the case for Android). This unit test was
based on a similar test for Android and therefore required some minor changes to
pass.

PTAL
