…_exists method before it ensures that $controller is not null

Today I tried PHP8 with Symfony 5.2. - by checking my routes with

bin/console debug:router

It throws

 method_exists(): Argument #1 ($object_or_class) must be of type object|string, null given

The reason is the configured auth route for the login API defined in routes.yaml:

authorization::login:
  path: '/login'

This route has no controller configured and the value of $controller in TextDescriptor::formatControllerLink in the FrameworkBundle is null. This method has a elseif condition with method_exists without a check if $controller is a string or object.
In PHP8 this throws an exception/error and did not work. This PR checks that $controller is not null before the method_exists check to prevent this failure.

I'm not sure how to test this in the existing Testsuite

Hey!

I see that this is your first PR. That is great! Welcome!

Symfony has a contribution guide which I suggest you to read.

In short:

  • Always add tests
  • Keep backward compatibility (see https://symfony.com/bc).
  • Bug fixes must be submitted against the lowest maintained branch where they apply (see https://symfony.com/releases)
  • Features and deprecations must be submitted against the 5.x branch.

Review the GitHub status checks of your pull request and try to solve the reported issues. If some tests are failing, try to see if they are failing because of this change.

When two Symfony core team members approve this change, it will be merged and you will become an official Symfony contributor!
If this PR is merged in a lower version branch, it will be merged up to all maintained branches within a few days.

I am going to sit back now and wait for the reviews.

Cheers!
