Get rid of Backbone wrapper for project list and single project views.
Review Request #9567 — Created Feb. 1, 2018 and submitted
Now that the application shell uses react, we can work on moving each of
the individual page views to do so. Since the project list and single
project views are already mostly migrated, these make a good first test
case. This change gets rid of the backbone view wrappers for those,
making them entirely rendered via react.
Flipped through the various pages and saw that they all rendered
correctly, and that the correct content was shown based on the opened
URL and links that were clicked.
