Datepicker popup's initial format is broken in angular 1.5.0

Please refer to #3025
Commented by rustygreen: "The datepicker popup's initial display value does not use the passed in format. After you select a value for the first time, it will display it property (using the passed in format)."

Angular 1.4.8 works fine but 1.5.0:

This appears to be an issue with current master as well, as can be seen here.

Looks like a workaround for now is to use init-date as the same value as your model, as shown here - need to investigate further though.
