`deleteRemoved: true` doesn't throw an error on Access Denied

[catamphetamine]

s3.deleteObjects() returns:

 {
      "Key": "xxx/yyy/zzz.html",
      "Code": "AccessDenied",
      "Message": "Access Denied"
    },

And the library just discards those types of errors.

That could happen when the user isn't assigned s3:DeleteObject role.
