Errors all returned as 'unknown'

[bitmage]

When wrapping errors, we are passing the error property, which ERARO doesn't do anything with. As a result any of the errors coming from this library have 'unknown' in their message body.

I resolved this locally by removing all usage of the ERARO library and just calling the standard callbacks with any errors we receive. e.g:

if (err) {return done(err)}

This seems to work splendidly. The seneca code receiving the callback values already wraps them with ERARO, and it already logs errors if necessary. So we can cut out code like this too:

seneca.log.error({code: 'save', tag: args.tag$, store: store.name, query: query, error: err})

Does this seem right? I'll submit a pull request if so.
