[10.x] Skip isParameterBackedEnumWithStringBackingType for non ReflectionNamedType

[vladimirmartsul]

#46483 May cause error Call to undefined method ReflectionUnionType::getName() at https://github.com/laravel/framework/blob/10.x/src/Illuminate/Support/Reflector.php#L151 if route action and parameter are defined as a union like this

public function edit(TwillModelContract|int $id): mixed {...}

(actual code from Twill CMS https://github.com/area17/twill/blob/3.x/src/Http/Controllers/Admin/ModuleController.php#L1131 )

This is because ReflectionUnionType and ReflectionIntersectionType don't have a getName() method, unlike ReflectionNamedType. So we need to skip checking if $parameter is not an instance of ReflectionNamedType.

Thanks @vladimirmartsul. Can we also add a test for this?

Yeah this is a BC that we're also experiencing in Filament. It seems to also affect any Livewire mount() method.

@vladimirmartsul I am so sorry for this issue. There wasn't any tests that broke for me when i did this change.

And i didn't know that we needed to adhere for a special case regarding union types and intersection types. Thank you for the bugfix anyway.

don't worry, at least we found them (who encountered them), we only could for future create for route registration regression tests to avoid such pitfalls?
