Whether the comments on manually graded questions were visible to
students should have been controlled by the 'Specific feedback' Review
option in the quiz settings. However, the quiz was not setting
$displayoptions->manualcomment, so it did not work.
This includes a check to see if there are 0 pages in the combined pdf,
catching exceptions and suppressing php warnings and errors from bad pdf files.
Also - Use TCPDF directly to check if pdfs are compatible. The previous check was
letting dodgy PDFs through which then failed at generation time. This way dodgy
pdfs will get run through ghostscript early and cleaned up.
It includes 2 more minor fixes:
- Escapes values sent to TinyMCE as it was breaking
when values contained double quotes.
- Adding seconds to the screenshots directory to
avoid using the same folder for multiple runs.
instance is has been used instead of cmid. This works as all id's are 1
in most cases, but not always.
accesslib_clear_all_caches_for_unit_testing was updated to clear the
$USER->access cache which would fail test when the wrong user's data was used.
Conflicts from extra tests in master:

This was breaking with oracle master/master replication. Fortunately all
the places that needed to be changed were private to datalib.php. There
is still some ordering by id there, but only places where we want a
consitent, rather than meaningful, order, so that is OK.
The queries changed by this patch all have subqueries in aggregate
queries that pull out the latest step for a question_attempt. Those
queries used to look for MAX(id) but now they look for
MAX(sequencenumber). This is equivalent (for databases where ids always
increase with time, except for auto-saved steps. In the past, an
auto-saved step might have been considered latest. Now the latest step
will always be one that has been properly processed. You can aruge that
this change is an improvement. Anyway, it is a moot point. All these
queries are only used in reports which are run on completed attempts,
where there will not be any autosaved data.
The restore cleanup code expects the mtime to be the time of extraction
not the mtime before archiving. If set to the old mtime, the restore
files may be cleaned up before the restore is complete.
This behaviour also matches the behaviour of the zip unpacker.
