Don't fail with a division by zero

phpdebt fails when there is no code. Let's inform the user and exit.

It'd be great if this was committed

Code like

  $module_handler = \Drupal::moduleHandler();
  $enabled_modules = $module_handler->getModuleList();

  foreach (array_keys($enabled_modules) as $module) {
    // All modules should have a recorded schema version, but when they
    // don't, detect and fix the problem.
    if (!isset($versions[$module])) {
      // Ensure the .install file is loaded.
      $module_handler->loadInclude($module, 'install');
      $all_updates = $update_registry->getAvailableUpdates($module);

(see update.inc)

results in

		-
			message: "#^A file could not be loaded from Drupal\\\\Core\\\\Extension\\\\ModuleHandlerInterface\\:\\:loadInclude$#"
			count: 1
			path: includes/update.inc

which it should not. There are instances where the first argument to loadInclude is a variable and in these instance PHPStan should not result in an error.

@sebastianbergmann what is the recommended way of testing that an error is triggered in PHPUnit 10? If you want to assert that an E_USER_WARNING is thrown by your code what is the best way to do this? Should you replace the error handler as above or is there a better way?

In order to get the folders listed I need to:

1. Close the project in PHPStorm
2. Delete .idea from the project
3. Re-open the project

At this point I can then checkout .idea to restore what the project ships with and re-open the project and everything works as expected. But this is super super awkward.

If I open this repository in PHPStorm immediately after cloning I don't see any folders - i.e. src/ which makes the project unusable.

I was looking through the dev tooling and I was interested in the use of mutation testing. However looking at the automated testing it doesn't look like infection is running as part of the automated testing. Am I missing something? Or should we either make it run or remove it as a dev dependency.

Fix spelling in phpstan.neon.dist
