Ordering of psr-4 namespaces can break code generation

[edmondscommerce]

If you specify your namespaces as:

    "autoload": {
        "psr-4": {
            "App\\": ["src/"],
            "EdmondsCommerce\\Vault\\": ["src/"]
        }
    }

Rather than:

    "autoload": {
        "psr-4": {
            "EdmondsCommerce\\Vault\\": ["src/"],
            "App\\": ["src/"]
        }
    }

Then you get the following error:

  Exception in EdmondsCommerce\DoctrineStaticMeta\CodeGeneration\Command\GenerateEntityCommand::execute: Exception in EdmondsCommerce\Doctrine  
  StaticMeta\CodeGeneration\Generator\EntityGenerator::generateEntity: Exception in EdmondsCommerce\DoctrineStaticMeta\CodeGeneration\Generato  
  r\EntityGenerator::createEntityTest: Exception in EdmondsCommerce\DoctrineStaticMeta\CodeGeneration\Generator\EntityGenerator::parseAndCreat  
  e: Exception in EdmondsCommerce\DoctrineStaticMeta\CodeGeneration\NamespaceHelper::parseFullyQualifiedName: The $fqn [EdmondsCommerce\[...]\  
  Entities\[...]] does not contain the project root namespace [App] - are you sure it is the correct FQN?
