LPS-44471

Hi Jorge,

when I use http://localhost:8080/c/portal/verify_email_address?ticketKey=... it works without plid and 
right now there is no exception in logs. 

There is another problem though, related to https://issues.liferay.com/browse/LPS-44557. This method needs to construct portal url and the only way is to get it from SessionContext or get HttpServletRequest from somewhere to call ```PortalUtil.getPortalURL(httpServletRequest)```.

Without it there is a wrong url: ```nullnull/portal/verify_email_address?ticketKey=09c9c62b-f79b-4dcd-b4cb-847487e177f1```, see the email below:
