changed incorrect key name in apple auth adapter tests

[mtrezza]

It seems that refactoring in 8e0e485 did not cover all parameters in apple auth adapter testing.

This PR should not have any functional impact.

closes #6858

@mtrezza Can you rebase from master to fix the tests? We should also update the changelog / release log with the refactoring. Should we add support for both client_id / clientId for backwards compatibility or can we ignore it?

done

We should also update the changelog / release log with the refactoring.

The change has been merged here on March 11 and released as Parse Server 4.2.0. I've retroactively added an entry to the change log for release 4.2.0.

Should we add support for both client_id / clientId for backwards compatibility or can we ignore it?

I don't think so. The change has been half a year ago, and even back then I would not have gone for backwards compatibility for something that only requires to change a key in the Parse Server config.
