In header nav, data-trackable is slightly broken due to incorrect key name

[callumlocke]

This line contains data-trackable="{{name}}" but the property name does not exist in the nav model, as far as I can tell. It should probably be {{label}} (?)

Same with this line – the template contains data-trackable="meganav | {{name}}", which renders as data-trackable="meganav | ".

I'm not sure if I've found every example, and I don't know this codebase, so I'll leave it to someone else to fix.
