URLConnectionTest changes for upgrade to OkHttp 2.7.5

These changes are required due to behavioral changes between OkHttp
2.5 and 2.7.5 which we want to accept for AOSP.

 - ProxySelectors now get a URL reconstructed from an Address (without
   path, query parameters and fragment) rather than  the full request
   URL. Proxy selection should not usually depend on those values:
   DefaultProxySelector cannot be configured to do so;
   PacProxySelector probably can be but it'd be a hack. In the absence
   of evidence that a significant number of clients rely on such a
   hack, we don't want to try to continue to support such behavior.

   This behavioral change affects testRedirectWithInvalidUrl() and was
   introduced by:
   github.com/square/okhttp/commit/c358656c8799d30fd422448153e99a5dd37e298a
   which no converts the URL to an Address, then back to a URL that's
   delivered to the proxy selector.

 - When clients set a Proxy-Authorization header on a request to a
   target server (e.g. google.com), previous versions of OkHttp would
   have copied that header to the request to the proxy that
   established a tunnel. It's unreasonable to support clients that may
   rely on this hack because this leaks the Proxy-Authorization header
   to the target server. Instead, the Proxy-Authorization header is no
   generated on the library level in response to a HTTP 407 Proxy
   authentication required status, which requires an additional round
   trip.

   Similarly, the request to the proxy to set up the tunnel used to
   have the User-Agent copied from the initial tunneled request.
   Instead, this request's User-Agent is now generated at the library
   level through Version.userAgent()

 - OkHttp 2.7 has new logic for CertificatePinning that we do not
   want to expose through Android's API surface; Android already
   has a different implementation of certificate pinning. This CL
   adds a sanity check that some Platform logic that OkHttp 2.7.5
   uses only for certificate pinning is not invoked in the common
   case of Http{s}URLConnections.
