Synchronous OnSubscribe Exception Skips Operators #1816

If an exception is thrown from a synchronous OnSubscribe it will skip the operators such as onErrorResumeNext.

For example:

Observable.create(subscriber -> {
 throw new RuntimeException("failed!");
}).onErrorResumeNext(throwable -> {
    return Observable.just("fallback value");
}).subscribe(System.out::println, t -> System.out.println("ERROR: " + t.getMessage()));

In this case onErrorResumeNext is not called and the error passes through.
