If desktop mode change also contains change in the pinning state,
recreate taskbar even if home screen always shows locked taskbar.
Without this, exiting desktop mode with transient taskbar to home with
"locked", i.e. pinned taskbar leaves taskbar in a broken state
(transient taskbar layout, with no background).
Bug: 406575227
Test: On desktop device, untoggle "Always show taskbar" in desktop mode.
When in desktop mode, click/tap the stashed taskbar handle to go
home. Verify that a proper pinned taskbar is drawn on home.
