In the mediawiki gateway fetch uses mw.Api which when calling ajax
returns a promise (not a deferred).
Thus .promise() here is unnecessary and happens to work because of
jQuery promises but it is not a standard method on JS promises so it
shouldn't be used on promises, only on deferreds.

Functional changes
- Show the default / error preview for all extract request failures
except those due to network circumstances (such as CORS) or no
connectivity (offline). Previously, the error preview was displayed
only for missing pages.
- FETCH_COMPLETE was previously only dispatched after FETCH_END. Now
it's also dispatched after FETCH_FAILED. The additional "fetch
complete" is not expected to impact logging. The states of success
are: START, END, COMPLETE. The new failure states are consistent with
success: START, FAILED, COMPLETE.
Testing
Errors may be stimulated in a number of ways including:
- Timeout: add a timeout field to RESTBaseGateway /
MediaWikiGateway.fetch().
http://api.jquery.com/jquery.ajax/
- Bad request: change MediaWikiGateway.fetch's action field to
`Math.random() > 0.5 ? 'query' : 'fail'` and RESTBaseGateway.fetch's
url field to
`RESTBASE_ENDPOINT + ( Math.random() > 0.5 ? encodeURIComponent( title ) : '%%%' )`.
- Desired Gateway can be configured in Gateway#createGateway().
- Note: T184534 describes a circumstance where cached previews may not
appear when offline. Disable browser caching to avoid confusion.

Update the placeholder extract and button text shown when a page preview
is unavailable from:
"popups-preview-no-preview": "Looks like there isn't a preview for this page"
"popups-preview-footer-read": "Read"
To:
"popups-preview-no-preview": "There was an issue displaying this preview"
"popups-preview-footer-read": "Go to this page"

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.
