better error message with "missing instance"

[rwst]

I tried with nodejs 8 and 10. I also installed the latest nvm and reinstalled. This is on OpenSuSE Leap 15. Credentials are configured.

  if (!program.instance) throw new Error('missing instance')
                         ^

• wb is the executable that is Wikibase-agnostic, and thus require to specify --instance http://my.wikibase.instance
• wd is the same executable, but bound to Wikidata, removing the need to set the --instance option

I guess the error message should give that hint

[rwst]

Agree. Thanks!

the new error message in v9.2.1:

missing instance
* Wikidata: use the 'wd' executable
* other Wikibase instances:
  * set the '--instance <http://my.instance>' option
  * or set the instance in config: 'wb config instance http://my.instance'
