[Bug]: Performance issue with ->not->toBeNull()

[cborgas]

What Happened

When I use expect($someEntity)->not->toBeNull() I'm noticing significant performance issues. I'm running "integration" tests with symfony and doctrine and asserting on doctrine entities. In some cases using not->toBeNull() will take upwards of 40s and removing it can reduce it to ~10s.

How to Reproduce

In a symfony application, write a pest test that extends symfonys BaseWebTestCase (docs here https://symfony.com/doc/current/testing.html#write-your-first-application-test) and write a test that asserts a doctrine entity exists.
