fix(mon-pages): clear search on reset filters

"Reset all filters" only dropped the filter conditions, leaving the
search query in place, so the listing stayed narrowed by whatever was
typed in the search box.

Clear the query along with the conditions and refetch explicitly: with
no condition set, the filter node does not change, so its watcher would
not fire and the cleared query would never reach the backend.
