replacing a custom label leads to no more log entries

When we add a second custom label, the logs stop working.

    log.Infof "set the batch label"
    log.AddLabel "batch" (sprintf "%d" batchId)
    log.Infof "batch label was set for the first time"
    let batchId = batchId + 1
    log.Infof "set the batch label a second time"
    log.AddLabel "batch" (sprintf "%d" batchId)
    log.Infof "batch label was set a second time"

Results in this where the last entry is missing.

let appender = new Google.Cloud.Logging.Log4Net.GoogleStackdriverAppender()
...

        member x.AddLabel key value =
            appender.AddCustomLabel(Google.Cloud.Logging.Log4Net.GoogleStackdriverAppender.Label(Key=key, Value=value))

I was expecting AddLabel to act like a Dictionary and replace the previous label with the same key.

Any chance you could provide a complete example in C# that would let us reproduce this easily?

@jskeet, I thought I saw on twitter that you were going to work on your F# skills!? 👽

Yes, will do.
