Title: Only show sidebar filter form if there are applicable filters

The sidebar filter/search form was being displayed even when there
were no applicable filters for a taxon. This resulted in the search
button appearing in the sidebar with no apparent purpose. In this commit,
the form is wrapped in an unless block that checks if there are filters.
If not, no form will be displayed.
