Admin: JavaScript error in schedule template change

[pitpalme]

Describe the bug
In schedule template change page there's a javascript error:

Uncaught TypeError: options is undefined

Maybe it originates from jQuery javascript

(function($) {
  $("#{{ inline_admin_formset.formset.prefix }}-group .tabular.inline-related tbody tr").tabularFormset({
    prefix: "{{ inline_admin_formset.formset.prefix }}",
    adminStaticPrefix: '{% static "admin/" %}',
    addText: "{% blocktranslate with inline_admin_formset.opts.verbose_name|capfirst as verbose_name %}Add another {{ verbose_name }}{% endblocktranslate %}",
    deleteText: "{% translate 'Remove' %}"
  });
})(django.jQuery);

in scheduletemplates/templates/admin/scheduletemplates/shifttemplate/shift_template_inline.html

To Reproduce
Steps to reproduce the behavior:

1. Login as admin or manager with permission to edit schedule templates
2. Make sure, at least one schedule template exists
3. Start to edit schedule template
4. Open Web Developer Tools or any other javascript console
5. See error

Additional context
As it seems, the error is not new to this release, but undetected in currently productive version too.
If intended feature is not used (anymore), code could be cleaned up and simplified.
