3607359-clear-facet-filters

Closes #3607359

Motivation

The "Clear Facet Filters" block only renders when the facet source uses the Pretty Paths URL processor. When switched to the default Query String processor, the block returns empty and the "Clear filter(s)" link never appears.

Testing steps

Add the "Clear Facet Filters" block to a Site Studio View and keep Query String processor in facets, the Clear Facet Filters will work after these changes.
