[Feature]Should provider a better error logger

[JiaLiPassion]

the information is from angular/angular#19923

Regular errors, such as HTTP errors, are correctly be logged as

ERROR HttpErrorResponse
When an error occur in a resolve guard, I get a weird stack trace:

ERROR Error: Uncaught (in promise): [object Object] 
   at resolvePromise (unpkg.com/zone.js@0.8.12/dist/zone.js:770)
    at resolvePromise (unpkg.com/zone.js@0.8.12/dist/zone.js:741)
    at eval (unpkg.com/zone.js@0.8.12/dist/zone.js:818)
    at ZoneDelegate.invokeTask (unpkg.com/zone.js@0.8.12/dist/zone.js:424)
    at Object.onInvokeTask (unpkg.com/@angular/[email protected]/bundles/core.umd.js:3913)
    at ZoneDelegate.invokeTask (unpkg.com/zone.js@0.8.12/dist/zone.js:423)
    at Zone.runTask (unpkg.com/zone.js@0.8.12/dist/zone.js:191)
    at drainMicroTaskQueue (unpkg.com/zone.js@0.8.12/dist/zone.js:584)
    at XMLHttpRequest.ZoneTask.invoke (unpkg.com/zone.js@0.8.12/dist/zone.js:490)

Expected behavior

I expect the resolve error to be logged / handled as any other error, so that we can send it to our error collector (Raygun).
