Revert of Make default media device ID salts random by default (patchset #13 id:260001 of https://codereview.chromium.org/1987643002/ )

Reason for revert:

Original issue's description:
> This results in different hashed device IDs on each session on embedders that don't have a specialized implementation of device ID salts such as WebView, Blimp and Content Shell. The new default helps prevent user fingerprinting on these embedders.
>
> Since the new default logic is basically the same as for Chrome incognito mode, Chrome's implementation of salts has been updated to defer to the new default on incognito mode.

A revert of this CL (patchset #1 id:1) has been created in
https://codereview.chromium.org/2068103003/ by guidou@chromium.org.

The reason for reverting is: Creating reland. The problem was a test that gets
the salt on the IO thread. It should be changed to the UI thread..
