Backport fix for "Passing a closed resource to Service parse or expect" to 2.2

[phil-davis]

Backport the code related to issue #297 from PR #296 to the 2.2 branch.

~And apply code-style changes that the latest php-cs-fixer 3.64 makes.~

php-cs-fixer 3.64 wants to apply trailing-comma to list(a,b,c,) as part of the latest Symfony code style. The old php-cs-fixer v2 does not know about that. So for this 2.2 branch we can lock the new php-cs-fixer to 3.63.2 so that it does not do any code-style changes. That lets the CI pass.

In future we will probably drop the support for PHP 7.1 7.2 7.3 and therefore can stop using php-cs-fixer v2. I will do that for a 2.3 series "some day".
