[testlib] make self.view() return raw output if no validator is used This will make it possible to parse and test view's output even if no validator is associated to the view's content type.

[tabs] do not use an ajax call to set cookie value, use jquery.cookie helper instead (closes #1944522)

[tabs] fix clic on tab that does nothing (closes #1942750) (there was an area around the text that would trigger the tab switch but not load the tab content)
