Improving portlet tests

Fixed problem with setting JSF portlet capabilities. There was throwed SWTLayerException when the portlet bridge was recognized in portlet runtime so there was not present text field for setting portlet bridge location.

Also enhanced messages showed in failure trace by adding description text and by storing informations about state of matching.

Running portlet on server was also improved. There is also added checking if there is any error in console's output.
