Port remaining VSMac blocker fixes.

- Noticed I hadn't ported all of the VSMac fixes to the master branch. This is me pulling the remaining fixes to solve any obvious blockers to the VS4Mac Razor experience.
- Note: VS4Mac doesn't work with just these set of changes. These changes simply enable VS4Mac to spin up our side of the Razor world and enable us to start parsing documents as users type. To fix the full Razor VS4Mac experience will require changes from other partner teams.
