Fix phpunit-wrapper from resetting variables in global scope in WrapperRunner

[proggga]

phpunit-wrapper has a problem

it's broken in WrapperRunner
phpunit reset global variables between runs
https://phpunit.readthedocs.io/en/9.3/fixtures.html#global-state

I've got problems with global state in phpunit and this fix helped me.
I tried to user WrapperRunner in my big project, and this helps

this fix prevent variables in phpwrapper (they all in global scope) from turning to null

(Also I removed assert here like in #539, I need this for passing all tests)

I get the idea of the issue, but please can you try to write a test for the bug?
It seems an important one, I'd like to prevent it from being reintroduced by a future refactor

It's problematic, cause phpunit-wrapper fails, and paratest doing nothing, he is waiting for some command or idk what. It will never complete.

That's ok: the pipeline has timeout-minutes: 3 set, so it will fail if a test is hanging forever.

Please try to write a test so I can see the pipeline failing
