Replace call to removed MWHttpRequest::factory (#493)

Since 1.34 MWHttpRequest::factory has been deprecated and
it was removed in 1.41. This patch replaces it with what I
believe is the obvious successor: HttpRequestFactory

This follows the recommended pattern from the mediawiki.org
docs[1] of creating the factory from MediaWikiServices and then
calls it with the options as before.
