Nest fixes (#5011)

* Updated Nest API to have logical names

* Fix NoneType not having replace method in NestSensor constructor

* Move name setting to constructor, in case zone.name causes IO.

* normalize is_online to online

* Updated python-nest API

* push is_* helpers down to python-nest, and use inheritence to implement rather than checking class name

* Update python-nest
