Various fixes to REST Person Service and Web Script Unit Test

- Delete people and authentications for users created in setUp()
- Modify person.lib.ftl so that it copes with firstName and lastName being undefined
- Modify people.post.js to use var.properties["propKey"]=value when adding person properties so that it copes with setting properties that don't already exist
