Possible bug related to new user_lastaccess and its behaviour

[mglaredo]

Using fordson ($plugin->version = 2020061800; $plugin->release = 'Moodle 3.9 Fordson v3.9 release 1.1';).

We consider as a bug that courses not accessed yet are showing on the top the list (before already accessed courses).

• Our investigation: we have realized that any courses never accessed have not the entry (db row) on the new user_lastaccess table.
• Wordaround: our moodle users have to enter into all their courses for obtaining a complete ordering view by lastaccess

Thanks in advance!
