Martin Sikora d9c4840a9c fix(router): cancel navigation when at least one resolver completes with no "next" emission (#24621)
This change aligns behavior for resolvers which return EMPTY. Currently EMPTY resolvers have inconsistent behavior:
- One resolver that returns EMPTY => won't navigate and just ends on ResolveStart router event.
- Two resolvers where both return EMPTY => throws "Error: Uncaught (in promise): EmptyError: no elements in sequence"
- Two resolvers where one returns a value and the other one returns EMPTY => Navigates successfully.
With this change any EMPTY resolver will cancel navigation.

BREAKING CHANGE: Any resolver which return EMPTY will cancel navigation.
If you want to allow the navigation to continue, you will need to update the resolvers to emit
some value, (i.e. defaultIfEmpty(...), of(...), etc).

Angular Router

Managing state transitions is one of the hardest parts of building applications. This is especially true on the web, where you also need to ensure that the state is reflected in the URL. In addition, we often want to split applications into multiple bundles and load them on demand. Doing this transparently isnt trivial.

The Angular router is designed to solve these problems. Using the router, you can declaratively specify application state, manage state transitions while taking care of the URL, and load components on demand.
