Can't use relative URLs with launchpadlib.Launchpad - generates URI object that breaks wadllib

Bug Description

I've got a test which looks something like:

  lp = launchpadlib_for("testing", user, version='devel')
  distro = lp.load("/ubuntu")
  series = distro.getSeries(name_or_version='edgy')

The lp.load() call returns the correct object, but the distro.getSeries() call fails with the following:

  File "/home/salgado/devel/launchpad/expose-blueprints/lib/lp/blueprints/tests/", line 251, in test_distroseries_all_specifications
  File "/home/salgado/devel/lp-sourcedeps/eggs/lazr.restfulclient-0.10.0-py2.6.egg/lazr/restfulclient/", line 543, in __call__
    url = self.wadl_method.build_request_url(**args)
  File "/home/salgado/devel/lp-sourcedeps/eggs/wadllib-1.1.5-py2.6.egg/wadllib/", line 585, in build_request_url
    return self.request.build_url(param_values, **kw_param_values)
  File "/home/salgado/devel/lp-sourcedeps/eggs/wadllib-1.1.5-py2.6.egg/wadllib/", line 701, in build_url
    if '?' in url:
TypeError: argument of type 'URI' is not iterable

If instead of using a relative URL I use launchpadlib._root_uri to construct an absolute one, the test pass. This might be a bug in wadllib, but I'm not completely sure that's the case.

lazr.restfulclient is turning the relative URL into a lazr.uri URI object, but wadllib assumes it's been given a string. We could either make sure a string is passed into wadllib, or make wadllib capable of handling lazr.uri URI objects. If the latter, we could either introduce a lazr.uri dependency, or just stringify a non-string object passed in where wadllib expected a string.

Retargetting to lazr.restful because resolving this bug requires fixing the lazr.resful source
