 * test_nodb: Start search engine
 * - without search-metadata.json
 * - without search.sqlite
 *
 * Ensure that :
 * - nothing explodes;
 * - if we change the order, search-metadata.json is created;
 * - this search-medata.json can be parsed;
 * - the order stored in search-metadata.json 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.
