[JWT] Handle when jwt_required is not returned in remote params

[nan-li]

Description

One Line Summary

When remote params did not return IOS_JWT_REQUIRED, assume off, unless this value has already been set.

Details

• remote params may not return the property IOS_JWT_REQUIRED.
• It is likely this feature is not enabled for the app, so we will assume it is off.
• However, don't overwrite the value if this has already been set.

Motivation

Identity Verification support should work with existing apps with no change.

Scope

Reading remote params and assuming a value

Testing

Unit testing

None

Manual testing

iOS 15 simulator on 17.2
Tested production and faking it receiving jwt_required and not receiving it.

Checklist

Overview

• I have filled out all REQUIRED sections above
• PR does one thing
  • If it is hard to explain how any codes changes are related to each other then it most likely needs to be more than one PR
• Any Public API changes are explained in the PR details and conform to existing APIs

Testing

• I have included test coverage for these changes, or explained why they are not needed
• All automated tests pass, or I explained why that is not possible
• I have personally tested this on my device, or explained why that is not possible

Final pass

• Code is as readable as possible.
  • Simplify with less code, followed by splitting up code into well named functions and variables, followed by adding comments to the code.
• I have reviewed this PR myself, ensuring it meets each checklist item
  • WIP (Work In Progress) is ok, but explain what is still in progress and what you would like feedback on. Start the PR title with "WIP" to indicate this.
