add phase model to the CipPlannerView

[smcalilly]

Overview

Fixes the CIP Planner, which was broken after we added the new Phase model. There's no issue for this.

Demo

This demo only works because my local database had existing Phase data that I created when working on PR #84.

Notes

Is there a better way to deal with the Project/Phase relationships using the ORM? select_related and prefetch_related wouldn't work, so I ended up querying it like this code implementation. Seems like that would be inefficient with a ton of unnecessary database queries?

Testing Instructions

• Visit the CIP Planner: https://ccfp-asset-d-cip-planne-eit48j.herokuapp.com/cip-planner/
• The values in phase column aren't exactly the same as the Phase model_choices since that data was pre-existing before we added the Phase model with model_choices. You'll see phase_1 instead of something like implementation. You can see my demo to see what the real values would look like.
