Make "component" a required property for a route

[danidee10]

What problem does this feature solve?

It improves the developer experience. Currently if a developer omits or misspells the component key of a route object ({ path: '/foo', Component: FooComponent }) Notice the Capital letter in Component.

No warning is shown (A blank page would be rendered since the path has no Component defined on it), There's already a warning if a developer tries to use a String as a Component. I believe this would also be useful as there's no point having a route that doesn't point to any Component.

What does the proposed API look like?

There's no change to the API.

Unfortuntaely, this is actually not possible because you can redirect in the beforeRouteEnter to somewhere else, therefore, component (or components or redirect) is not required 🙁
