To address #14, the explainer has been updated to express the way to deal with the no fetch handler case and the empty fetch handler case.

To deal with WICG#14, the explainer has been updated.
It started to have the section that explains how the static routing API works with no fetch handler case.  Its explanation on handling the empty fetch handler has been updated.

@sisidovski @azaika Can I ask you to review the explainer update?
@domenic FYI.

- clarified "cache" won't run the fetch handler.
- said "return a promise" instead of "raise exceptions" because `addRoutes()` returns a promise.
- clarified why "empty fetch handler" should not return a promise rejected with a TypeError.
As suggested in the comment, I have clarified the empty fetch handler behaves different for fetch-event and race-network-and-fetch-handler cases.
The "cache" source should look up a request from the cache storage even if there is no fetch handler.
Moreover, it does not need to run the fetch handlers regardless of cache hit or cache miss.
On the other hand, the "fetch-event" and "race-network-and-fetch-handler" sources run the fetch handlers.
`addRoutes()` should return a promise rejected with a *TypeError* if these sources are used while no fetch handlers are set.
