Expected union of types in Contacts.ts - listContacts()

[ropinheiro]

In Contacts.ts, in the body of the listContacts() function, line 51 has:

(inError: Error, inDocs: IContact[]) => { ...

This gives me an error, because this.db.find seems to expect the inError to be a union of Error and null.

For the error to disappear, I had to change my code to this:

(inError: Error | null, inDocs: IContact[]) => { ...

A similar problem occurs in the same file, for the deleteContact() function.

this seems to fix #22 and #23 for me. i was having the same issues building on the cli on a mac

Thank you

Do you guys get these errors for addContact and deleteContact too?
And it seems just adding | null doesn't fix the issue.
