Hapi 6.0 no longer invalidates auth strategy on registration of route

[biant]

In previous versions server.route() would validate the name of the configured auth strategy and throw an exception if the name was not already registered with server.auth.strategy()

To reproduce check the this unit test in hapi-auth-basic:
https://github.com/spumko/hapi-auth-basic/blob/master/test/index.js#L349

@biant Good catch. This test was moved to hapi-auth-basic when we split it and it should have stayed in hapi. I moved it here so you can drop it from basic.

@hueniverse removed the unit test from hapi-auth-basic
