fix: Make sure default status is set

[tkyi]

Context

Seeing some errors in API logs:

TypeError: Cannot read property 'includes' of undefined
at EmailNotifier._notify (/usr/src/app/node_modules/screwdriver-notifications-email/index.js:96:48)

Need to make sure build status object exists. Seems like some users are setting email settings like below, which is not handled correctly by this plugin:

settings:
    email:
        addresses: [[email protected], [email protected]]

Objective

This PR:

• updates dependencies (jenkins-mocha, hapi, eslint, etc)
• adds default statuses
• pulls in hoek

Does this need changes from users whose sd.yaml is currently valid ? is this backward compatible ?

@jithin1987 it shouldn't need changes unless they have empty array for addresses or statuses
