Changing way of test page loading in utc_blink_ewk_view_contents_pdf_get test

Loading google.com page by ewk_view_url_set() resulted with error:
"Unsafe attempt to load URL  from frame with URL
http://www.google.pl/?gfe_rd=cr&ei=qzWUVKGhG4jBVLOZgsAP.
Domains, protocols and ports must match"
It looks like google.com page changed recently
and made cross-domain call in the test.
