    icon-theme: Drop loading_themes recursion check
    
    This was added in 0b1c9b7cc26d293477a6823a40d3e1feebbd6df7 to protect
    against reentrancy from the theme-changed signal, but we only emit this
    from an idle these days, so thats not necessary anymore, and the recursion
    check was causing issues with the async operations where a different
    thread loading the theme caused the calling thread to thing the
    theme is valid.
