SoupSession: give password to GSimpleProxyResolver

After setting the "proxy-uri" property on a SoupSession with embedded basic auth (e.g. http://user:pass@example.com), libsoup does not make use of the auth and ends up emitting an "authenticate" signal on receiving 407. Calling soup_auth_anthenticate() with the same credentials then works, but it should've made use of the auth from the beginning to avoid the round trip.

This seems to be a regression from fb09bf93 (https://bugzilla.gnome.org/show_bug.cgi?id=680273), during the transition to GSimpleProxyResolver. The issue is that libsoup uses `soup_uri_to_string_internal`, which doesn't embed the password in the resulting string.

The attached patch changes this, making sure to retain the previous behaviour in all other cases.
