fix(cheminfo-publish): show error log when npm publish fails

[stropitek]

I published generator-cheminfo with those changes and it worked fine

Was able to see npm publish error, fix and then publish

execa() does not work with commands without specifying the full path

You have to use execa.shell()

Sorry for the bad diff... Prettier...

That's not true. See how I used it here for example:

https://github.com/nodejs/node-core-utils/blob/74a3a8991de444576a6a04f5f863971c6f9e611a/lib/update-v8/updateV8Clone.js#L23

I assumed because I had an ENOENT error when trying it with npm

> execa('npm', ['--version']).then(console.log)
Promise {
  <pending>,
  domain:
   Domain {
     domain: null,
     _events:
      { removeListener: [Function: updateExceptionCapture],
        newListener: [Function: updateExceptionCapture],
        error: [Function: debugDomainError] },
     _eventsCount: 3,
     _maxListeners: undefined,
     members: [] } }
> { stdout: '6.4.0',
  stderr: '',
  code: 0,
  failed: false,
  killed: false,
  signal: null,
  cmd: 'npm --version',
  timedOut: false }

There seems to be something wrong in your test. What was the command?
