Remove mobile tests

We don't have a "mobile" section of the site anymore that has separate
templates, so let's just remove all the mobile tests.
Fix test_search.py

This fixes the tests in test_search.py so that they both pass and don't
require other tests to run before them in order to pass.

Fixes #151

it affects.
