hgweb: don't raise an exception when displying empty repos

The nullid node claims it's in the default branch, but the branch dict
is empty.  This fixes the main symptom from issue696, but we may want
to set branchtags()['default'] = nullid somewhere for empty repos.

#!/bin/sh

hg init test
cd test

echo '[web]' > .hg/hgrc
echo 'accesslog = access.log' >> .hg/hgrc

echo % Without -v
hg serve -a localhost -p 20063 -d --pid-file=hg.pid
cat hg.pid >> "$DAEMON_PIDS"
if [ -f access.log ]; then
    echo 'access log created - .hg/hgrc respected'
fi

echo % With -v
hg serve -a localhost -p 20064 -d --pid-file=hg.pid -v
cat hg.pid >> "$DAEMON_PIDS"
