Changes proposed in this Pull Request:

Resolves NPPM-2974 (cosmetic follow-up from the #488 / NPPM-2966 review).

The run_invite_request() test helper hooks wp_redirect with a zero-parameter
closure. Give it an explicit $location parameter so it matches the filter
signature and the sibling capture_link_invite_log_events() helper in the same
file. No behavior change — the closure still throws to unwind the handler.

How to test the changes in this Pull Request:

1. n test-php --filter Test_Group_Subscription_Invite — still green (8 tests).

Other information:

• Have you added an explanation of what your changes do and why?
• Have you written new tests for your changes, as applicable? — n/a, test-only signature tweak
• Have you successfully run tests with your changes locally?

Pull request overview

Updates a PHPUnit test helper in newspack-plugin’s WooCommerce Subscriptions group-subscription invite tests so its wp_redirect filter callback accepts the expected argument, avoiding argument-count failures when the filter is invoked.

Changes:

• Adjust the run_invite_request() redirect-capture closure to accept the redirect location parameter (matching the approach used by the similar helper in the same test file).
