Summary:
Two minor changes here:
- Replace `get/setUser()` with `get/setViewer()` for consistency with everything else.
- `getViewer()` now throws if no viewer is set. We had a lot of code that either "should" check this but didn't, or did check it in an identical way, duplicating work. In contrast, very little code checks for a viewer but works if one is not present.
Test Plan:
- Grepped for `->user`.
- Attempted to fix all callsites inside `*View` classes.
- Browsed around a bunch of applications, particularly Calendar, Differential and Diffusion, which seemed most heavily affected.
