David Hoyt d011e96028 souphttpsrc: Improve error messages 
Before they contained the URL before the actual failure. The other
way around makes more sense and we do the same in other elements
like filesrc.

Fixes bug #627289.

/**
* SECTION:element-souphttpsrc
*
* This plugin reads data from a remote location specified by a URI.
* Supported protocols are 'http', 'https'.
*
* An HTTP proxy must be specified by its URL.
* If the "http_proxy" environment variable is set, its value is used.
* If built with libsoup's GNOME integration features, the GNOME proxy
* configuration will be used, or failing that, proxy autodetection.
* The #GstSoupHTTPSrc:proxy property can be used to override the default.
*
* In case the #GstSoupHTTPSrc:iradio-mode property is set and the location is
* an HTTP resource, souphttpsrc will send special Icecast HTTP headers to the
* server to request additional Icecast meta-information.
* If the server is not an Icecast server, it will behave as if the
* #GstSoupHTTPSrc:iradio-mode property were not set. If it is, souphttpsrc will
* output data with a media type of application/x-icy, in which case you will
* need to use the #ICYDemux element as follow-up element to extract the Icecast
* metadata and to determine the underlying media type.
*
* <refsect2>
* <title>Example launch line</title>
* |[
* gst-launch -v souphttpsrc location=https://some.server.org/index.html
* ! filesink location=/home/joe/server.html
* ]| The above pipeline reads a web page from a server using the HTTPS protocol
* and writes it to a local file.
* |[
* gst-launch -v souphttpsrc user-agent="FooPlayer 0.99 beta"
* automatic-redirect=false proxy=http://proxy.intranet.local:8080
* location=http://music.foobar.com/demo.mp3 ! mad ! audioconvert
* ! audioresample ! alsasink
* ]| The above pipeline will read and decode and play an mp3 file from a
* web server using the HTTP protocol. If the server sends redirects,
* the request fails instead of following the redirect. The specified
* HTTP proxy server is used. The User-Agent HTTP request header
* is set to a custom string instead of "GStreamer souphttpsrc."
* |[
* gst-launch -v souphttpsrc location=http://10.11.12.13/mjpeg
* do-timestamp=true ! multipartdemux
* ! image/jpeg,width=640,height=480 ! matroskamux
* ! filesink location=mjpeg.mkv
* ]| The above pipeline reads a motion JPEG stream from an IP camera
* using the HTTP protocol, encoded as mime/multipart image/jpeg
* parts, and writes a Matroska motion JPEG file. The width and
* height properties are set in the caps to provide the Matroska
* multiplexer with the information to set this in the header.
* Timestamps are set on the buffers as they arrive from the camera.
* These are used by the mime/multipart demultiplexer to emit timestamps
* on the JPEG-encoded video frame buffers. This allows the Matroska
* multiplexer to timestamp the frames in the resulting file.
