Validate completion executes more than once; every 120 seconds.

[MaximusMcCann]

I call validate(on: view, completion: completion). If I sit there (pretend the user is slow/reading something) the completion continuously calls about every 120 seconds, or, eventually the captcha dialog (img selection) shows up.

I'm not really sure I understood what's going on. Please, correct me if I'm wrong:

Is your completion closure being called multiple times when the validation takes over 120s? If so, is it taking a long time to load, or is the app idle on the image selection screen?

How can I reproduce this issue? Should I just wait when the challenge shows up?

[MaximusMcCann]

I click a button that calls validate. The captcha comes back successfully, but if I just sit there eventually it completes again with a new captcha. And it's every 120 seconds. This even happens if I call stop() as well. This does not involve the image selection.

Attached is a simple example. Set your api key and url in the ViewController class. Build + run. Click the button that says "Click me". Wait a few minutes and watch the debug logs/label on the app screen.

Additionally, adding self?._recaptcha?.stop() after case .success(let captcha): does not prevent the continued callbacks

I found the issue, now I'm working on a solution.

Apparently, Google's API keep calling some URL, and the lib is understanding that as a cue to validate again.

Thanks for the input, nevertheless.

@MaximusMcCann could you check if the branch fix/consecutive-completion-calls fixes the issue for you, please? It'd be great if you could approve #30 if it does.

@fjcaetano Appears fixed. Here's the total debug logs after 12+ minutes
