add received_header test, cleaned up PR #59 (#61)

- deps: pin versions
- test: load DBs so we get test results
- test: use correct assert syntax
- index: turn off watchForUpdates, due to warning:
- (node:52697) MaxListenersExceededWarning: Possible EventEmitter memory
leak detected. 11 change listeners added to [StatWatcher]. Use
emitter.setMaxListeners() to increase limit

Closes #59

- [x] tests updated
