 * test_nodb: Start search service without existing settings file.

 * Ensure that :

 * - nothing explodes;

 * - if we change the order, search.json.mozlz4 is updated;

 * - this search.json.mozlz4 can be parsed;

 * - the order stored in search.json.mozlz4 is consistent.

 * Notes:

 * - we install the search engines of test "test_downloadAndAddEngines.js"

 * to ensure that this test is independent from locale, commercial agreements

 * and configuration of Firefox.
