All setUp(), tearDown(), setUpBeforeClass() and tearDownAfterClass()
must, always, call to parent, to ensure that everything is properly
set and cleaned.
While in a lot of situations this is not needed (parents may not
have anything to run), with PHPUnit >= 10 this can become more
important because we are going to move the reset code from current
placement @ runBare() to setUp()/tearDown().
Note that all the changes performed in this commit have been detected
and fixed by moodle-cs (ParentSetUpTearDownSniffTest).
The original implementation of group filtering introduced in MDL-80565
assumed that the log table existed in Moodle's own database. This is not
the case of the database logstore, or any similar logstore implemetning
the database \core\log\sql_reader interface.
Furthermore this check was also applying the SQL when the user had the
`accessallgroups` capability, or when the course was not in SEPARATE
groups mode (no groupmode and/or visible groups).
