Remove _initialize method and replace it by delegating constructor.

* This is more straight forward with C++11 and the way todo.
* Also move some initializations to the header file.
* Remove assignment of empty String("") since this is an assignment with
  a default constructed object which is already default constructed.
* Remove reset of unique_ptr: They are per default initialized as empty nullptr.
