Monitor streams can be identified based on the stream.monitor property.
They should not be identified based on application name, because that
may be localized, and the previous code does not work properly on
non-English locale.
The "saved headset profile" is taken as the profile that was active when
the headset mode deactivates. So in case the user switches profile during
the time when the Communication input stream is active, the selected
profile is remembered next time.
