Use null coalescing to routes resolution in FeatureTestTrait::call

[paulbalandan]

Description
This change will allow us to not be constrained in using FeatureTestTrait within the context only of FeatureResponse. We can also use this on other test cases, like CIUnitTestCase. This also resolves phpstan's error "Ternary operation always return true."

If one of the intents is to be able to run this trait on CIUnitTest could you maybe add an example as a test case?

[paulbalandan]

Sure do.

I'm confused. HomeTest does not fail locally.

PS C:\Users\P\Desktop\Web Dev\CodeIgniter4> vendor/bin/phpunit -v --filter HomeTest

OK (1 test, 1 assertion)

@paulbalandan It was failing because we use Services::reset() in other tests. And it wipes out the default routes config.
