hg: allow hg.parseurl(url, None)

In many places hg.parseurl is called with a url and "opts.get('rev')",
suggesting the second, optional argument can be None. Because opts['rev']
usually defaults to [] this never happens in practice.

However, extensions don't necessarily behave the same, but do copy this
pattern.

Also, include wider hg.parseurl tests, beyond a demonstration of the problem.

#!/bin/sh
hg init
echo This is file a1 > a
hg add a
hg commit -m "commit #0" -d "1000000 0"
ls
echo This is file b1 > b
hg add b
hg commit -m "commit #1" -d "1000000 0"
hg co 0
# B should disappear
ls
