The parameter $parameters of the method get of the Phalcon's DiInterface can be array or null.

/**
     * Resolves the service based on its configuration
     *
     * @param string $name
     * @param array $parameters
     * @return mixed
     */
    public function get($name, $parameters = null);

According to this parameter Di container tries to create service. If we have an array of dependencies in our definition, such as

'group' => [
         'className' => '\Acme\Group',
         'arguments' => [
             [
                 'type' => 'service',
                 'service' => 'myComponent',
             ],
         ],
     ],

than we can get \Acme\Group without parameters $group = $container->get('group', null);. In this case we get class Group with injected myComponete.
If we use $group = $container->get('group', []);, than we have got an error " [ArgumentCountError] Too few arguments to function Acme\Group::__construct(), 0 passed and exactly 1 expected ".

This pull request adds an ability to use parameters from the container's definition, to create a service.
