Tracker: If TRACKER_MANUAL_LINK is None, do not show any help link

Wikimedia

Problem

If Tracker sysadmin sets TRACKER_MANUAL_LINK configuration variable to None, a link to help page is still shown (leading to nowhere).

Proposed solution

Do not display help link when TRACKER_MANUAL_LINK is set to None.

Student is expected to send a patch for wikimedia-cz/tracker repository, hosted at Wikimedia Gerrit. When claiming task on GCI website, student should claim a respective Phabricator task as well.
