    searchbar: ignore action-state-changed signals which are not for us
    
    I'm pretty sure this is a regression lower in the stack, probably GLib
    or GJS; we connect to the detailed 'action-state-changed::search' signal
    on the GApplication action group, but our callback is also invoked when
    other action's state changes.
    Workaround this by ignoring all the emissions that are not for us.
