Filters are cleared when the home page is visited and not when an document is

If you go to a collection, set a filter, then click the home click, then go to another collection, the filters are no longer set.

However if you go to a collection, set a filter, click on an item, then use the breadcrumbs to go back to the collection, the filters are still set.

I thought this was the most intuitive option, but it might be better to clear the filters whenever the page is left.

@yefim @AlexeyMK what do you think?
