* Renamed WebRequest::exportUserSession -> RequestContext::exportSession.
Updated the only callers of this new function.
* Init the user with User::newFromId() instead of relying on the session
(which breaks when things like CentralAuth are enabled).
* Made RequestContext::exportSession() include the user ID.
* Removed now-redundant user ID checks in upload jobs.
* Added unit tests for the session import function.

Looks like someone messed with RequestContext when I wasn't looking at it.
WikiPage is a representation of the Title. It should not be possible for wikipage
to point to a different title than the context's title.
Fix this issue by unsetting WikiPage when setting title and updating title when
setting wikipage.
