fix(test): mark ContentManagerTest as a DB test and more fixes

The phpunit workflow failed on Nextcloud 36 with PHP >= 8.4:

  TypeError: OC\Files\Config\UserMountCache::__construct():
  Argument #1 ($connection) must be of type OCP\IDBConnection, null given

- Extend PHPUnit\Framework\TestCase instead of Test\TestCase.
- Add the DB group, since the test uses the real IJobList, and declare it
with the #[Group] attribute.
