Consistently use formatTemplate()
Consistently use formatTemplate()

`formatTemplate()` is a method that can be overwritten by plugins. It is also a method that can be called by the user to manually build customized form elements (e.g. adding extra elements to a `submitContainer`).

Right now FormHelper inconsistently uses `formatTemplate()` or `$this->templater()->format()`. It should in all cases use `formatTemplate()` however, as to provide the same experience to the user in both cases (internal or external use).
Furthermore, overwriting `formatTemplate()` is a powerful tool for plugins, only if it is also consistently called internally.
