Title: As Piwik user I would like to disable summary row and report truncate if truncate value is negative

In my opinion Truncate filter shouldn't truncate and add summary row if truncate parameter is negative. I'm not sure how it connects with other Piwik reports, but when I was checking this then everything seems to behave normally.
