fix for bug #384671: when resetting the history sidebar view, don't use applyFilter()

this is needed for bug #380735, for when we persist day and host container
open state in the history sidebar.

additionally, call load() instead of using .place directly to avoid doing queriesToQueryString() only to call queryStringToQueries().
