Better test coverage for prerender sessionStorage merging. 

Actually test that the sessionStorage behaved correctly. Also, add a test for a
conflict case. Ensure the page still loads.

BUG=none
TEST=PrerenderBrowserTest.PrerenderPageNewTab,
     PrerenderBrowserTest.PrerenderSessionStorageConflict
