Fix up the testcases

Please check if transliteration of Hebrew in LnaguageUtilsTest is
correct. It works just fine if you follow the mapping in LanguageUtils.

Test all transliteration in LanguageUtils only, the test in
DeviceCommunicationServiceTest does not need to be done for every
language.

Also use assertEquals(expected, value) instead of assertTrue(expected.equals(value));
