pass around SavedSearchId and SavedChartSearchId

otherwise people loose binding to the loaded saved search and
can not update it - our UI doesn't allow to update existing
saved search without loading it first, but loading resets all
changes.

Changing sort order on Results.html page was loosing
saved search id.

Updating tickets via Bulk.html was loosing saved search id.
drop unused variables
