TT#47017 Fix return page after closing edit phonebook form

And also fix description for Location creation form

All Customer controller fix implemented a little out of common way to handle customer detatils forms
Forms on customer details  page use common code on the bottom of the customer/details.tt. Phonebook forms use helpers/datatables forms related code. It allows to avoid stashed "description" parameter, that is totally related to View (template) and generates correct name for the edit form.
