Use resolveRegistration to lookup firebase auth providers.

[m-basov]

Description

When using emberfire with Ember 2.12 authentication is not working.

Before code used to find provider class utilized method lookup. It tries to find firebase-auth-provider:<provider> factory but nothing was found.

const ProviderClass = getOwner(this).lookup(`firebase-auth-provider:${providerId}`);

Instead we need to use resolveRegistration to find auth provider.

const ProviderClass = getOwner(this).resolveRegistration(`firebase-auth-provider:${providerId}`);

This PR should fix Issue #493.

I'm still getting this issue @kolybasov trying to run a basic session open. ember2.12.1 emberfire2.0.6

this.get('session').open('firebase', { provider: provider});
