Title: Text report was using an undefined attribute to render the summary (only when the option "showOnlySummary" was marked as true)

I believe that this class was refactored or the ```$this->outputStream``` was copied from another class and has been forgotten.

That was raising warnings and errors, because ```outputStream``` attribute does not exists.
