    // Code below makes sure that the DateTimeShortcuts.js is loaded exactly once
    // regardless the presence of AdminDateWidget
    // How it worked:
    //  - First Django loads the model formset with predefined widgets for different
    //    field types. If there's a date based field, then it loads the AdminDateWidget
    //    and it's required media to context under {{media.js}} in admin/change_list.html.
    //    (Note: it accumulates media in django.forms.widgets.Media object,
    //    which prevents duplicates, but the DateRangeFilter is not included yet
    //    since it's not model field related.
    //    List of predefined widgets is in django.contrib.admin.options.FORMFIELD_FOR_DBFIELD_DEFAULTS)
    //  - After that Django starts rendering forms, which have the {{form.media}}
    //    tag. Only then the DjangoRangeFilter.get_media is called and rendered,
    //    which creates the duplicates.
    // How it works:
    //  - first step is the same, if there's a AdminDateWidget to be loaded then
    //    nothing changes
    //  - DOM gets rendered and if the AdminDateWidget was rendered then
    //    the DateTimeShortcuts.js is initiated which sets the window.DateTimeShortcuts.
    //    Otherwise, the window.DateTimeShortcuts is undefined.
    //  - The lines below check if the DateTimeShortcuts has been set and if not
    //    then the DateTimeShortcuts.js and calendar.js is rendered
