subrepo: change default path in hgrc of subrepo after cloning

Previous behavior was to put in the cloned subrepos the path found in the original main repo.
However it isn't valid for relative path and it seems more logical to reference instead the subrepos
working copy path of the original main repo.

"""hooks for integrating with the CIA.vc notification service

This is meant to be run as a changegroup or incoming hook. To
configure it, set the following options in your hgrc::

  [cia]
  # your registered CIA user name
  user = foo
  # the name of the project in CIA
  project = foo
  # the module (subproject) (optional)
  #module = foo
  # Append a diffstat to the log message (optional)
  #diffstat = False
  # Template to use for log messages (optional)
  #template = {desc}\\n{baseurl}/rev/{node}-- {diffstat}
  # Style to use (optional)
  #style = foo
  # The URL of the CIA notification service (optional)
  # You can use mailto: URLs to send by email, eg
  # mailto:[e-mail]
  # Make sure to set email.from if you do this.
  #url = http://cia.vc/
  # print message instead of sending it (optional)
  #test = False

  [hooks]
  # one of these:
  changegroup.cia = python:hgcia.hook
  #incoming.cia = python:hgcia.hook

  [web]
  # If you want hyperlinks (optional)
  baseurl = http://server/path/to/repo
