Updated mediawiki/extensions
Project: mediawiki/extensions/MobileFrontend  939aa1e2833c01738d70b94f7881e4af1152f442

Migrating all use of M.pageApi.getPageUrl to mw.util.wikiGetlink

mediawiki.util is loaded by deafult on mobile in the head, so there's
no reason we need to have our own function for URL retrieval.

Explicitly declaring dependancy in mobile.stable.common (although
it's loaded anyway).

Marking M.pageApi.getPageUrl as deprecated (should be removed at some
point along with related unit tests).
