Previously, the test made no meaningful assertion. It seems that the
intention was to ensure that some elements were present on the page, but
all the assertions did was verify that the corresponding
`ElementFinder`s were defined. The `ElementFinder`s would always be
defined, even if there were no corresponding elements on the page. In
fact, some of the `ElementFinder` selectors were incorrect, so they did
not match any actual elements.
This commit fixes the tests by fixing the `ElementFinder` selectors and
asserting that the elements are actually present on the page.
