Failed promise before calling allOf is not failing the wrapped promise.

Expected Behavior

Promise.allOf(promises) should fail as long as one of the promises fails, no matter it is already failed before calling the allOf or after.

Actual Behavior

If one Promise in promises is already failed before calling allOf, the failure is ignored.

How to reproduce

A workflow like following will ended successfully.

        val promise1 = Async.procedure { throw RuntimeException() }
        val promise2 = Async.procedure {
            // do something else
        }
        someActivity.doSomething()

        Promise.allOf(promise1, promise2).get()

Analysis

AllOfPromise#addPromise only handles the promise that is not completed.

Specifications

• Version: 1.20.0

Start at AllOfPromise#addPromise and reproduce the Kotlin workflow from the issue, focusing on a promise that has already failed before Promise.allOf is called. Verify that the wrapped promise fails for both pre-completed and later-failing inputs, and add or update coverage for those cases.
