[TASK] Remove not needed TemplateService code

The TemplateService class provides its own wrap()
function which is exactly the same as in cObj.
The only instances where the wrap() method is used
is in the MenuContentObjects - however, they can
also access the wrap() function via cObj.

The MenuContentObjects are now using the cObj
function so the duplicate code in TemplateService
can be deprecated.
