This function deletes an existing folder. deleteDirectory specifies
      whether the existing folder is regular folder, or a folder
      directory.
This function only removes the actual folder in the mail
        account. The folder
        object is not affected, the application is still
        responsible for destroying the object, when it is no longer
        needed.
