Changing access control level of a property called "open" fails

[lyricsboy]

Hi, and thanks for making AccessControlKitty!

I tried it on the following input:

struct OperatingHours {
    let open: String
    let close: String
}

I ran "All Public" on it to get:

public struct OperatingHours {
    let public: String
    public let close: String
}

Instead of let public: String I expected public let open: String.
