[1.6.0-beta01+] clearMediaItems() is no longer clearing the notification

[Enjot]

Version

Media3 pre-release (alpha, beta or RC not in this list)

More version details

Hi,

I am using MediaSessionService and MediaControllers.
While on 1.6.0-alpha03 and previous versions, clearMediaItems() also cleared the notification.
While on 1.6.0-beta01 and later versions, clearMediaItems() doesn't clear it.

I did a little investigation and I found that this commit is causing the issue.

Devices that reproduce the issue

Any Android device

Reproducible in the demo app?

Yes

Reproduction steps

In demo-session app change this line in MainActivity.kt:78

        browser?.sessionActivity?.send()

To

        browser?.clearMediaItems()

Now, CURRENT PLAYLIST button on the first screen will clear the playlist.
Play some playlist, navigate back, and click this button.

Expected result

The notification will disappear.

Actual result

The notification stays up, but it's not responsive at all.
