Fixed wrong return type in phpdoc

Update laravel/helpers.php

Huge performance increase on Eloquents relationships

The e-helper and the __-Helper used the core-classes. 
So if I would like to override them, the helpers would still use the core-classes.

Fix a tiny typo

Auth token now nulled on logout

[#1261] get_key now pulls from $original instead

This is in reference to issue #1261, where Model->get_key() returns
the key from the $attributes instead of from the $original property.
This breaks the functionality of a model with a primary key that may
change, as the SQL generated will be something like:

UPDATE `model` SET `key` = 'new-key' WHERE `key` = 'new-key';

Which won't update the model in the database.
