VE-1511 Integrate new API for getting template suggestions

https://wikia-inc.atlassian.net/browse/VE-1511
It's not. When the promise is resolved a callback is required that gets the template data as a parameter. You have an anonymous function that gets template data and then simply calls the populateOptions function with template data. This is simpler: 

this.getMostLinkedTemplateData().done( ve.bind( this.populateOptions, this ) );
