I think the original thought of setting the "name" to just be call is good enough.

Making the name unique is more of a "maintain backward compatibility" as previously, the "name" was provided by developer in `routes.json`, and by convention, they were unique across all routes.

Turns out that mojito-shaker uses the name property to group rollups per route entry. We can revert it to being set to "call" only, and document that in order to ensure uniqueness, the app should generate and associate a named identifier to it.
