batch actions JS error for nested table_for in index page

[follmann]

Since I use nested table_for I had an error that the CheckboxToggler js code threw:
Error: 'toggle all' checkbox not found

That rendered batch actions dysfunctional.

The culprit seems to be in batch_actions.js.coffee:

if $(".paginated_collection").find("table.index_table").length
  $(".paginated_collection table").tableCheckboxToggler()

should (probably) be:

if $(".paginated_collection").find("table.index_table").length
  $(".paginated_collection table.index_table").tableCheckboxToggler()

This is fixed here #1993
