hgweb: use scmutil.binnode() to translate None to wdir hash (issue5988)
I left some of ctx.node() calls unchanged as they seemed unlikely to be
workingctx, or passed to diff functions where None is the default value.
Note that a None revision can also cause a similar problem, but I'm not sure
if we can simply bulk-replace ctx.rev() with scmutil.intrev(ctx) as there's
large hole between tip revision and wdir revision. If such pair were passed
in to xrange() for example, we would waste CPU time.
