This PR will fix an error and a risky warning that are thrown when running the PHPUnit tests:
Error in mod_adaptivequiz_adaptiveattempt.xml file: it throws an error for those sites that have more than 50 modules in their databases (this also applies for the second file).
Risky warning in mod_adaptivequiz.xml file: the first record in the _coursemodules table was defined with a wrong number (13 instead of 1) in the field instance. I also added a new record for this table based on the number of records that were define in the adaptivequiz table (3, not 2), so they are now in sync.
