[DI] Fix 'undefined index' error, when entering scope recursively

Imagine two scopes:

```php
$container = new Container();
$container->addScope(new Scope('foo'));
$container->addScope(new Scope('bar', 'foo'));
```

Enter the same scope twice recursively:

```php
$container->enterScope('foo');
// not entering bar in between
$container->enterScope('foo');
// prints warning: undefined index: bar
// at Symfony/Component/DependencyInjection/Container.php:341
```

The problem exists, but the fix looks wrong to me. We should keep the scoped services even with nested scopes. Right now, and even after your patch, we loose some information.

---------------------------------------------------------------------------

by ludekstepan at 2012-11-28T16:38:05Z

I don't know how to fix properly, the patch above is just a workaround.

Without the patch, it's not possible to simply create a child scope of the "request" scope, because "enterScope" would fail upon every forward between "request" and nested "request" unless "bar" scope was entered prior to forward.

---------------------------------------------------------------------------

by stof at 2012-11-28T16:51:50Z

@fabpot why would it be wrong ? If the nested scope was not active when entering a subrequest, there is simply nothing to save

Any news about this one ? =)

@fabpot could you explain which info we are loosing ?

- [x] Add a UT

I won't have time to add a test before next Friday but this PR could save some debugging (especially with Silex & Closures)

---------------------------------------------------------------------------

Probably related to https://bugs.php.net/bug.php?id=62976, I need to do some more investigation - I use 546. anyway the fix is valid for whatever php version.

---------------------------------------------------------------------------

by vicb at 2013-02-10T10:24:46Z

This **is** related to the PHP bug mentioned above, see http://3v4l.org/Q6WKj:

```
Output for 5.3.18 - 5.3.21, 5.4.8 - 5.5.0alpha4
bool(false)

Output for 5.3.0 - 5.3.17, 5.4.0 - 5.4.7
Notice: Object of class Klass could not be converted to int in /in/Q6WKj on line 9
Notice: Object of class Closure could not be converted to int in /in/Q6WKj on line 9

Is it possible to add a test?
