The Binary datafilter was returning a single value where all parts of
the API expect an array of values. This was working in most places by
fluke as this value was a single-character string, so doing $value[0]
returned the value. However, it was not working when deciding which
option to mark as selected when re-displaying the filter.
This change makes the filter return an array containing a single integer
value to match the rest of the API, then internally selects that single
value for comparison when deciding if an option should be selected.
1.9 backups used current plugin version as oldversion.
But quiz uses some hardcoded version numbers when processing
restore which is lower then current plugin number, so some quiz
logic was ignored.

restore_quiz_stepslib.php
Within the forum_get_discussion_neighbours() function of forum
when the discussions timemodified (last post) is the same, there
is a bug that does strange things when calculating the prev and
next discussions.
Note that, in real life, this is really hard to achieve, but in tests,
when multiple discussions and post can be created by generators in the
same second (specially when the test machine is quick), chances of
facing that problem are higher.
By adding 1 second wait, we ensure that the discussions won't have
the same timemodified (last post) and workaround the problem.
No mater of that, the problem deserves an issue to be created
so we guarantee from code that it also works ok when the same
timemodified (last post) situation happens.
Note that normally this doesn't matter much, but there are situations
when we want the discussion list ordering fully consistent /
deterministic.
Specifically, when discussions (or forum posts )are created in the
same second, or when the discussion titles are repeated, or 2
discussions have the same number of votes... (any criteria in general),
in the context of testing, we don't want the order
to be non-consistent, so we need to provide an extra sorting
criterion to make it fully deterministic.
So, in this case, we are adding a sort by discussion.id <<DIRECTION>>
that is an unique value, primary key... so cheap to calculate and,
that way, when the 1st sorting column has repeated values, the id
will decide.
Associate column headings of user report tables to the user ID that the
report is being generated for. This will prevent duplicate IDs for the
report columns when multiple user report tables are displayed on the
User report page.
* The table cells mentioned in the `headers` attribute of other table
cells need to be using the table header <th> tag. Otherwise, HTML
validation fails.
when `log_out` is called from `\core\oauth2\client` it will delete the refresh token,
what it actually needs to use it to get a new access token
actually logging out is not needed here, the only thing we need to make sure is,
the invalid access token is removed from the session
that is done by storing `null`
