Use correct tsconfig.json in pure tests

This will change the pure tests Mocha setup to actually use the
`tsconfig.json` located in the `test` directory. Before, it was using
the root-level `tsconfig.json`. To ensure we are still using mostly the
same settings, this will extend the `test/tsconfig.json` from the
root-level `tsconfig.json`.
