Add 3ds2 url to list of completion URLs so callbacks work correctly.

[skyler-stripe]

Summary

• Adds the 3ds2 URL to the list of completion URLs. This means that the webview will close when not given a return URL. Previously it would get stuck. This is really only the case when using Stripe.handleNextAction or PaymentLauncher.handleNextAction.
• Our normal confirm flows with both classes append a return URL which makes 3ds2 not land in this situation. handleNextAction does not do this, so we need add to our list of URLs so the activity result is fired correctly.

Motivation

• 3DS2 isn't finalizing after authentication completed #5059
• https://jira.corp.stripe.com/browse/RUN_MOBILESDK-1023

Testing

• Added tests
• Modified tests
• Manually verified

Created a PI with a next-action of 3ds, and hard coded it both with PaymentLauncher and Stripe. I confirmed that the webview would not hang and fires the callback correctly.

This may be for a future PR, but can't we just match all urls that are https://hooks.stripe.com, then we don't need to maintain this list?

[skyler-stripe]

There's also https://hooks.stripe.com/three_d_secure/authenticate which triggers a different flow. So unfortunately not :(

[skyler-stripe]

This does feel like a value that should come from a server rather than be hard coded though. Hopefully we can add it later this year after we have that capability.
