Crash when using debounce (100%)

[jakobmygind]

Hi, in a very simple use case debounce seems to crash, but it might just be me using the cx proxy wrong?

This code crashes with EXC_BAD_INSTRUCTION:

 let pub = PassthroughSubject<Int, Never>()
        
        pub
            .debounce(for: 2.0, scheduler: DispatchQueue.global().cx)
            .sink(receiveValue: {
                print($0)
            })
            .store(in: &subscribers)
        
        (0...10).forEach(pub.send) //Crashes here: Thread 1: EXC_BAD_INSTRUCTION

Fixed. The problem is actually caused by DispatchQueue, not Debounce

@luoxiu The problematic code was not tested. We should introduce code coverage analysis.

Thank you! Quick dispatch, so to speak :)
