Title: Correct filter while posting empty values

Empty values in POST caused bad catalog searches with empty results ;
On JS side, while refreshing the filter on Booking Center with no category, canRefresh was failing silenciously (JS error, no refresh) ;
Finally, booking_filter.pt was oddly constructed.
