SDK Token: Remove UUID format from application_id.

[tomw1994991]

Looking at the mobile sdk docs here

The application_id field of sdk_token does not seem to be a UUID:

The application_id is the "Application ID" or "Bundle ID" that was already set up during development.

For iOS this is usually in the form of com.your-company.app-name.
To get this value manually, open xcode ios/YourProjectName, click on the project root, click the General tab, under Targets click your project name, and check the Bundle Identifier field.
To get this value programmatically in native iOS code, see Stack Overflow Page.

For Android this is usually in the form of com.example.yourapp.
To get this file manually, you can find it in your app's build.config. For example, in android/app/build.gradle, it is the value of applicationId.
To get this value programmatically in native Java code, see Stack Overflow Page.

Given that this is a bug making the endpoint unusable, we'll deliver soon a fix as a minor update.
