fixes #6497: New Organization: Focus should exist in Name field

It's almost the same code, when ```attr.to_s == 'name'``` is **true**, ```:focus_on_load``` is **true** too.
When it's **false**, ```:focus_on_load``` is whatever value it had before.
Here's what's different, if it's **false**, and ```:focus_on_load``` didn't have any value before, ```:focus_on_load``` is **false** instead of nil. 

Since nil in ruby is equivalent to false in a condition (try ```!!nil``` for instance), in practice it's the same, but it's not *exactly* the same behind the scenes.

@orrabin change it to what Ohad suggests, :smile:
