Reproduction steps

I will attempt to follow the rules for creating a full zip. However, in case that fails, I will also attach a patch here. The patch adds sign-in and sign-out functionality to the automotive demo app.

• apply the patch
• launch the app in an automotive environment, preferably the one specified above, but it should not matter.
• tap "sign in"
• play any track
• back out to the home screen
• tap on the settings cog wheel
• tap on "sign out"

Expected result

Playback should stop and the user should be presented with a clean sign-in screen, as seen when the app was first launched.

Actual result

The sign-in screen has a playbar with default metadata superimposed over the top of it.

Media

The patch uses the media in the demo app:

0001-Signed-out-ghost-playbar.patch
