[FIX] web: reset offset to 0 when searching for records

Scenario: Go to any list or kanban view: go to next page and set a
filter that matches less that 'limit' record (e.g. less than 40),
but at least one. No record will be displayed, because the offset
is kept for the search_read.

This rev. ensures to reset the offset to 0 when a search is done
using the searchview.
