Also, fix README

Apparently, this is needed to run 'nix' inside tests (e.g. start corenlp)

Take into account the async nature of createProcess. Add proper watch
so that we monitor that coreNLP is running.

Fix bug in DB transaction rollbacks in the presence of domain-specific errors

Closes #480

See merge request !420

This commit fixes the bug with DbTx rollbacks and domain-specific
errors. What we do now is throwing an exception during the evaluation of
`DbFail`, to later catch it _after_ `withTransactionM` has performed a
clean rollback, and only at that point we call `throwError`.

This also means that we need to catch `DbTx` errors via the `MonadError`
interface, not via the exception-handling interface, to get proper
rollback behavior.

errorWith has a `HasNodeError` constraint but the name was misleading.
