timeout() operator always emits error, even if given a promise or another observable

[igorsechyn]

RxJS version: 5.0.0-beta.10

Code to reproduce:

const rx = require('rxjs');
const source = rx.Observable
    .of(42)
    .delay(5000)
    .timeout(200, Promise.resolve(42));

const subscription = source.subscribe(
    function (x) { console.log('Next: %s', x); },
    function (err) { console.log('Error: %s', err); },
    function () { console.log('Completed'); });

Expected behavior:
Output: Next 42
Actual behavior:
Output: Error: [object Object]
Additional information:
According to documentation the timeout operator, if passed a promise or another observable, should emit this value. Currently, regardless of what is being passed into the operator, the value is being emitted as error

You may need timeoutWith to supply continuing observable when timeout occurs. due to polymorphic behavior of timeout, it has splitted into timeout and timeoutWith (refer #244 for background, #245 for implementation)

Awesome, thanks. Maybe worthwhile updating the documentation and/or the migration guideline

[kwonoj]

Yes, seems migration guide missing it, need to be updated.
