pull: fix passing credentials in URL. Previously, the parsed URL - with credentials removed - was used for instantiating a new svnremoterepo instance. One option for fixing this is using the unparsed URL for this instantiation. An even better option, however, is to simply reuse the instance passed to the function as `source'.
