Subject: [PATCH] refactor(ErrorObservable): clarify an error type `E` for
 ErrorObservable.

BREAKING CHANGE - `ErrorObservable.create()` (`Obserbable.throw()`)
takes a new type parameter `E` that express a error type instead on old
one's `T`. Their functions return `ErrorObservable<E>`.
It is still the drived type of `Observable<any>`, it's not changed from
old one. But it contains the error typed as `E` now.
