chore: cleanup all test files (#293)

## Changes made
- Removed all unused imports, and made sure type imports were labeled
correctly
- Updated all comparisons to be more strict
- Simplified loops to remove unneeded closure functions
- Removed all explicit `any` types
- Updated how strings were defined to follow general TypeScript best
practices

## Notes
- We definitely want some kind of linting setup for this repo. I'm going
to bring this up when Blueberry has its next team meeting next week
