Fixed UTC for ewk_view_add_with_session_data.

Fixed UTC for ewk_view_add_with_session_data.

The test was expecting that the webview won't be created
for the NULL session data, while according to WebKit-EFL code,
this should create empty webview. Current implementation
does exactly this, so the test case had to be fixed.
