always exit with code 1

[seblapela]

It always retunr with exit code 1 while there is no error.. I have added these two console log lines:

linkCheck(link, opts, function (err, result) {
                console.log("err:  " + err)
                console.log("result:  " + result)

give the following output:

err:  null
LinkCheckResult {
  link: '../Developer-Guides/Observability.md#getting-access-to-bifrost',
  statusCode: 200,
  err: null,
  status: 'alive'
}

So the err object is null, but the exit code is still 1.
If I comment out the last callback call around line 211 it returns with code 0

Could be related to #369. I am observing the same issue that the check always fails. Last version for me that worked was 3.12.2
