[lijiarui]

Expected behavior

use function Contact.findAll() to get all the contact list.
It should return all my real contact, shouldn't include oa account

Actual behavior

Contact.findAll() return the contactLIst includes oa account.

Wechat(webwxApp) always treat all contact(include OA account) as the same.

So the implementation of Wechaty in the current version, OA Account is also a Contact.

I'll close this issue for now. In the future, you can purpose a new design to separate the Contact type, and we can discuss based on that.
