    cool#8278 sfx2 lok: fix unexpected non-json sidebar status update
    
    Open an Impress document via LOK, open the slide layout sidebar, click
    the toggle icon so it gets closed: the toggle icon will signal that the
    sidebar is open, when it's closed already.
    
    This is a regression from commit
    aaf6ce108e91b1504befe19afcee471e3316ae7a (cool#7492 sfx2 lok: set
    language/locale on async sidebar update, 2024-01-11), previously we
    always emitted LOK_CALLBACK_STATE_CHANGED callbacks with plain text
    payloads for the sidebar, where the locale with implicit (with all its
    issues), but the above scenario worked fine.
    
    Fix the problem by making SidebarController::disposeDecks() consistent
    with SwitchToDeck(), so now we always emit JSON payloads for the sidebar
    deck changes.
    
    An alternative would be to improve the code around extractUnoCommand()
    in online.git to handle a mix of plain text and JSON payloads, but the
    plain text payload is tricky to extend, so using more JSON payloads
    sounds like a better fix.
