Awaiting to a filtered ReactiveProperty about unirx

[kordian-kowalski]

I think I figured it out:
LINQ-like functions, including Where return an IObservable which when awaited, by default returns after the observable stream is completed (the value being the last value in the stream)

For anyone interested, you can do things like:

await someReactiveProperty.Where(...).Skip(1).First();

or

await someReactiveProperty.SkipLatestValueOnSubscribe().Where(...).First();
