After portlet removal, Calendar is not destroying a javascript poller code that requests current time to server once per minute

The code that request the time to server was added in LPS-65412

This issue is also reproduced in case of having SPA enabled and moving from a page with a calendar to other page without any calendar. The requests that get current time from server will be executed without having calendar and a warning trace will be written to liferay log

Steps to reproduce

1. Create a new page
2. Install Calendar in new page
3. Open it in "Day" or "Week" view
4. Stay in the new page and open browser "Developer tools" => "Network" tab
5. Wait two or three minutes
6. You will view a request to following URL once a minute

   /c/portal/layout?p_l_id={PLID}&p_p_cacheability=cacheLevelPage&p_p_id=com_liferay_calendar_web_portlet_CalendarPortlet_INSTANCE_xxxxxxxxxxxx&p_p_lifecycle=2&p_p_resource_id=currentTime
   

7. That requests are also written in tomcat log file localhost_access_log.2017-xx-xx.txt
8. Remove Calendar from page
9. Wait two or three minutes
10. Open browser "Developer tools" => "Network" tab and check again the requests to /c/portal/layout
    • Expected behavior: No requests to /c/portal/layout are done after removing Calendar portlet. No warnings are written to liferay log
    • Wrong behavior: Requests to /c/portal/layout are done after removing Calendar portlet and they return error "400 bad request". A warning is written to liferay log for each request

11. You can also check the requests in localhost_access_log.2017-xx-xx.txt file
