Subject: [PATCH 2/2] gxps-images: clear the error before trying to load an
image again

In gxps_images_get_image() we first try with the image file extension,
and if that fails then we try guessing the content type. If the image
load failed the first time, the GError might be filled already, so we
need to clear it before passing it to create functions again.
