Enable nette/di lazy mode (#465)

See the [blog post](https://blog.nette.org/en/one-line-in-configuration-will-speed-up-your-nette-application-how-is-that-possible).

The speedup is tiny in my case, if any at all, as the database connection is already created on-demand only (since 7766444 #14) but it generally seems like a good idea.

Needed a bit of a refactoring because `RouterFactory::getLocaleRouters()` returned an empty list in tests when the lazy mode was enabled because `RouterFactory::createRouter()` has not been called yet.
