Feature request - Encounter search "select all" selects all results and not just what's displayed on a single page.

**Expected behavior**
In react encounter search, "select all" selects all of the results.

**Current behavior**
"Select all" only selects the displayed results. Users have to click on every page of results and click the select all button again for every page of results.
