Any time you have multiple views, you *must* declare which view you
want Catalyst to use by default.

To accomplish this, in your application config just provide:
default_view: TT (or whatever your default view is)

You can put this in MyApp.pm or myapp.(conf|yml) as a top level
configuration option.
