Method dom.element#renameNode() should clear #getName() cache

[Piotrek Koszuliński]

element = CKEDITOR.dom.element.createFromHtml( '<div></div>' );
element.renameNode( 'p' );
assert.areEqual( 'p', element.getName() ); // actual: 'div'

Can be also checked in browser with the below code:

var editor = CKEDITOR.replace( 'editor1' , {});	
editor.on( 'instanceReady', function( ev )
{					
element = CKEDITOR.dom.element.createFromHtml( '<div></div>' );
element.renameNode( 'p' );
console.log(element.getName());
});

Reproducible from CKEditor 3.2.2 (Before this version error was thrown).

I've added a new test that guarantees the efficiency of the trick used in this fix. Interesting trick, btw.
