5.2.4 release broke filterrific_sorting_link generation when current sorting is not present

ruby: 3.1.3 rails 6.1.7.2

Saw that the 5.2.4 release was available but it broke some specs I have. When I tried it out on an internal feature it was actually broken.

It happens on initial page load when there are no sort options.

ActionView::Template::Error (undefined method `end_with?' for nil:NilClass

        current_sort_direction_indicator: (current_sorting.end_with?("_desc") ? opts[:descending_indicator] : opts[:ascending_indicator])
2:   <table class="table">
3:     <thead>
4:       <tr>
5:         <th><%= filterrific_sorting_link(@filterrific, :id) %></th>

From the looks of it I think it's this line of code:

current_sort_direction: if current_sorting
                                  current_sorting.end_with?("_desc") ? "desc" : "asc"
                                end,
current_sort_direction_indicator: (current_sorting.end_with?("_desc") ? opts[:descending_indicator] : opts[:ascending_indicator])

I can open a PR with the fix.
