fix(config/jest): set Jest root to '.' in config, but use '<rootDir>/src' for project

Change Jest root directory to ./ instead of './src' and './test' because specifying a root that
doesn't exist throws an error. Use '<rootDir>/src' for this project to avoid weird mock errors
from `jest-haste-map` on CI... may need to revisit this.
