Stephen Niedzielski 8ca0cf2088 Fix: preview page URL for 404 RESTBase responses ... Functional changes: - Require page URL when constructing a PreviewModel null object. These models have valid titles and are used to display a preview when an extract is unobtainable. When presented with an empty URL, their linkage incorrectly pointed to the browser's current URL. Additional tests were added to verify the fix. - Check missing title in addition to falsy response in RESTBase gateway and update the test assertion to check title. It isn't clear if this can happen in the wild. - Forbid state mutation in the conclusion of MediaWikiGateway.getPageSummary() with a call to Deferred.promise(). This is consistent with the rest of repo including RESTBaseGateway. http://api.jquery.com/deferred.promise/ Nonfunctional changes: - Collapse two RESTBase gateway 404 tests into one as the scenarios and expectations were very similar. - Add failure HTTP status to 'MediaWiki API gateway handles API failure' test stub HTTP response for consistency with other cases. - Add nullity expectations to JSDocs touched and fix a couple typos throughout. - Make the gateway tests a little more consistent by collapsing Deferred variable usage where appropriate. This change is necessary to the completion of T183151 which uses the PreviewModel null objects for additional error cases.
