Witness search does not work properly

1. Open governence operations -> witnesses tab
2. Focus witnesses table and scroll down 2 pages
3. Focus Search input and type gtg, then press [Search] button

List does not contain gtg. There is a simple explanation why: because view is positioned at second page and gtg should be display at first. I think the solution is always reset page to first one during changing a search conditions (including Clear option).
