Display same items in mobile menu on User Profile page as on desktop

Summary:
Display same items in mobile menu on User Profile page as on desktop. (The code did not make too much sense anyway here?)

Also remove special but dysfunctional "Calendar" item in mobile view: The resulting URI does not work even if the calendar application is installed. If it ever worked, it should be moved to the default desktop sidebar anyway and not be a mobile-only menu item.

Closes T15224

Test Plan: Open http://phorge.localhost/people/ and http://phorge.localhost/p/username and http://phorge.localhost/people/manage/1/, change screen width to less and more than 920px, check at menu items in left bar (>920px) and right upper corner (<920px).
