[Ed Lee :Mardak]

The test failures started on the 20th after an export including bug 1481680 which changed the test to run with search shortcuts, so it seems like a timing issue of top sites appearing later than originally expected by the test.

-content.openContextMenuAndGetOptions(".top-sites-list li:first-child")
+content.openContextMenuAndGetOptions(".top-sites-list li:not(.search-shortcut)")

Consistently wait for the same non-search non-placeholder site to get context menu.
