Problem/Motivation
Follow up from #2745179: Uncaught exception in link formatter if a link field has malformed data - the question of whether we should log an error was brought up but there are some differing opinions.
Also following up from #3340154: Link-widget throws exception when rebuilding a form with an invalid uri and whether to log error from the widget when a user without "link to any page" permissions tries to edit an entity with a malformed link URI.
