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.

#!/usr/bin/env python
#
# simple script to be used in hooks
#
# put something like this in the repo .hg/hgrc:
#
#     [hooks]
#     changegroup = python "$TESTDIR/printenv.py" <hookname> [exit] [output]
#
#   - <hookname> is a mandatory argument (e.g. "changegroup")
#   - [exit] is the exit code of the hook (default: 0)
#   - [output] is the name of the output file (default: use sys.stdout)
#              the file will be opened in append mode.
