context.status: wipe deleted/unknown/ignored fields when reversed

It makes no sense to request reverse status (i.e. changes from the
working copy to its parent) and then look at the deleted, unknown or
ignored fields. If you do, you would get the result from the forward
status (changes from parent to the working copy). Instead of giving a
nonsensical answer to a nonsensical question, it seems a little saner
to return empty lists. It might be best if we could prevent the caller
accessing these lists, but it's doubtful it's worth the trouble.

Tests if hgweb can run without touching sys.stdin, as is required
by the WSGI standard and strictly implemented by mod_wsgi.
