Memory session adapter and dotted keys

[fedeisas]

Hi! I found a bug when using memory session adapter. I use in-memory session when running unit tests and they were failing.

use lithium\storage\Session;
use lithium\storage\session\adapter\Memory;
use lithium\storage\session\adapter\Php;

Session::config([
    'default' => ['adapter' => new Php()],
    'memory' => ['adapter' => new Memory()]
]);

Session::write('a.b', ['my' => 'data'], ['name' => 'default']);
var_dump(Session::read('a', ['name' => 'default']));
// array (size=1)
//  'b' => 
//    array (size=1)
//      'my' => string 'data' (length=4)

Session::write('a.b', ['my' => 'data'], ['name' => 'memory']);
var_dump(Session::read('a', ['name' => 'memory']));
// null

I think both adapters should have the same behavior regarding dotted keys.

You're right this should be changed. I've labelled this as an enhancement as it does not prevent the core framework from working correctly.

Ok.
