remove @access and unnecessary $name

`@access` is not used anymore. Removed the last bits.

$name is not necessary. Files are not baked anymore with it - and the core should reflect that.
The remaining `public $name = 'JoinAsJoinB';` etc show more clear where it is actually required to modify/adjust the name param (2 Fixture classes to be exact).

Travis is fine, but seems to be linked wrong below: https://travis-ci.org/dereuromark/cakephp/builds/8848229
