Stop checking for lot name for keyword serach test

This test is testing that searching for an id in the search box
works, it doesn't actually need to select a lot.
The previous iteration of this test started from the `/g-cloud`
page, and clicking the lot would bring you to the `/g-cloud/search`
page.
