test-obsolete: use 'log -T {node}' instead of 'id --debug -i' to lookup hash

I ran into a case when adding a test where there were cryptic hg command line
errors.  I eventually traced it back to 'hg id' printing debug messages before
the hash:

    invalid branchheads cache (served): tip differs <hash>

This method should eliminate any other output except the node.

# A dummy extension that installs an hgweb command that throws an Exception.

from mercurial.hgweb import webcommands

def raiseerror(web, req, tmpl):
    '''Dummy web command that raises an uncaught Exception.'''

    # Simulate an error after partial response.
    if 'partialresponse' in req.form:
        req.respond(200, 'text/plain')
        req.write('partial content\n')

    raise AttributeError('I am an uncaught error!')

def extsetup(ui):
    setattr(webcommands, 'raiseerror', raiseerror)
    webcommands.__all__.append('raiseerror')
