Re: [w3c/manifest] Add installation prompt control flow (#417)

Ok, spec text now matches reference implementation. However, I'm still bothered that `ev.userChoice` can be left unresolve in case of an error. 

We have two options: 

 1. We add a new enum value to AppBannerPromptOutcome, like "unknown". 
 2. Or, maybe more correct, we call reject() on the `[[\userChoice]]` promise.
