Fix default authentication config keys

[ekryski]

Summary

The default config key was changed to authentication and was not updated here. This fixes that. This isn't a breaking change for anyone using v2 of the generator and/or are passing their auth config explicitly when configuring auth plugins:

const config = app.get('auth');
app.configure(authentication(config));

but it will be for people that migrated to the new version of auth and still have a config file with:

"auth": {
   // auth config values
}

instead of:

"authentication": {
   // auth config values
}

For that reason, this and the associated PRs will need to be major releases:

• use the correct config key name. Closes #20 authentication-jwt#21
• use the correct default config key. Closes #21 authentication-local#22
• using correct auth key. Closes 17 authentication-oauth1#18
• using correct auth key. Closes 23. authentication-oauth2#24

Why not ease the burden with a var authConfig = app.get('auth') || app.get('authentication') and merge that in, instead? We'll have some cleanup work to do as tech support, otherwise.

@marshallswain Ah shit sorry. I didn't even see your comment. That's a good idea.
