Fixed the wrong cookbook used in LWRP and corrosponding readme pages

Was having issues with the main repo. Fixed and tested this forked repo in a librarian git cookbook. 

Tested with the following contents:

default.rb:

```
include_recipe "chef-user"

chef_user_account 'biziz' do
  comment   'My User'
  gid 		'sudo'
end
```

metadata.rb
```
depends 		 'chef-user'
```
