[2.x] Fixing Backtrace not found error if project dirname endswith pest

[Carnicero90]

What:

• Bug Fix
• New Feature

Description:

Currently, \Pest\Support\Backtrace::backtrace() is skipping every file which str_contains($trace['file'], 'pest'.DIRECTORY_SEPARATOR.'src', so that for whatever reason the base folder of the project's name ends with pest (i.e.: testpest, which was actually my folder name), it fall back to throw ShouldNotHappen::fromMessage('Backtrace not found.');. I guess DIRECTORY_SEPARATOR.'pestphp'.DIRECTORY_SEPARATOR.'pest'.DIRECTORY_SEPARATOR.'src' should be safe enough to avoid that issue.

Hey, @Carnicero90 ! Thanks for your PR.

Could you fix the errors here, please? Thank you.

[Carnicero90]

Yeah I'll look into that, but I'm not sure it is related with my commit, since I get the very same error even if I run make test or composer test:unit in a fresh clone of the original repo (on branch 2.x)

@devajmeireles are you positive that those issue are caused by something in my PR? Cos I am getting the very same error (a DatasetMissing exception whenever you are trying to set the value for the test in a describe context via beforeEach()->with(values);) even without any change at all in the source code. Still, I could try to fix that, but it looks like a completely different issue, which deserves a dedicated issue/pr. Dunno if I am missing something trivial, my apologies if that's the case.
