Describe the bug

Something I found while trying to debug an issue I had - not using that function at the moment so it's not high priority for me but thought I'd share it with you regardless.

BTThreeDSecureClient.initializeChallenge only completes if lookupResponse cannot be converted.
Reason for that is - completion is not passed to self.process(lookupResult: lookupResult, configuration: configuration).

private func process(lookupResult: BTThreeDSecureResult, configuration: BTConfiguration) as well as performV2Authentication within it use merchantCompletion that is only set when calling startPaymentFlow.

I assume the async version would hang there forever, as it never calls continuation.resume.

To reproduce

1. Call btThreeDSecureClient.initializeChallenge
2. Wait for completion to be called.

Expected behavior

Completion should be called.

👋 Hello @Przeszaf - thanks for bringing this to our attention.

The method BTThreeDSecureClient.initializeChallenge() should not be used by 99% of our merchants integrating with 3DS. Instead, follow our developer docs for how to integrate. That method was added for a specific merchant with an edge-case, server-side integration.

We will put up a PR addressing the callback issues you found as well as clarify the docstrings of that method!

A fix for this was merged and will be released with the next braintree_ios v6 release!
