Fix test cases broken by updating to PHPUnit 9.x and Symfony 5+

- PHPUnit 9 removed the assertArraySubset function, which now exists as
  a separate pacakge. Slightly bizzare move, but at least there's an
 easy fix.

- Fix test cases broken by the introduction of DumpCompletionCommand in
  Symfony 5's default command list, which adds 'completion' to the list
  of command results:

    https://github.com/symfony/console/blob/6.1/Command/DumpCompletionCommand.php

- Removed long deprecated option `syntaxCheck` from the phpunit.xml
  file, which now causes an error.

- Ignored new result file created by running test cases under PHPUnit 9
