Cannot get a name and parameters for RoleProviderPluginManager

Hi! I have fatal error with PHP7.0.18 + ZF2.5.3 + ZF-Commons/zfc-rbac 2.6.2

Fatal error: Uncaught Zend\ServiceManager\Exception\ServiceNotFoundException: ZfcRbac\Role\RoleProviderPluginManager::get was unable to fetch or create an instance for in /var/www/vhosts/pf-portal/vendor/zendframework/zend-servicemanager/src/ServiceManager.php:555

The issue in \ZfcRbac\Factory\RoleServiceFactory

with this code:

$roleProvider = $pluginManager->get(key($roleProviderConfig), current($roleProviderConfig));

The internal pointer in array $roleProviderConfig is in the end of array, because of that key($roleProviderConfig) and current($roleProviderConfig) return null.

There is two options to fix it on place:

1. Reset internal pointer in array to the beginning:

reset($roleProviderConfig);
$roleProvider = $pluginManager->get(key($roleProviderConfig), current($roleProviderConfig));

2. Use different functions, which work without pointer.

$roleProvider = $pluginManager->get(array_keys($roleProviderConfig)[0], $roleProviderConfig[array_keys($roleProviderConfig)[0]]);

I think first is better and it is good practice to get first element of associative array.

My config looks like this:

'zfc_rbac' => [
    'role_provider' => [
        'ZfcRbac\Role\ObjectRepositoryRoleProvider' => [
            'object_manager' => 'doctrine.entitymanager.orm_default',
            'class_name' => 'Module\User\Entity\Role',
            'role_name_property' => 'name',
        ],
    ],
],
