registerAllFlagsListener does not work on iOS with secondaryMobileKeys

[emin93]

Describe the bug
When using registerAllFlagsListener with a non-default environment (secondaryMobileKeys), the updates are not being delivered. Switching back to the default environment fixes the issue and the updates are being delivered again.

This only happens on iOS, on Android it's working. And it does not happen when using registerFeatureFlagListener.

To reproduce

const client = new LDClient();
client.configure(
    {
        mobileKey: 'production-key',
        secondaryMobileKeys: { test: 'test-key' },
    },
    { key: 'test-user' }
);

client.registerAllFlagsListener('example-1', console.log); // This works
client.unregisterAllFlagsListener('example-1');

client.registerAllFlagsListener('example-2', console.log, 'test'); // This does not
client.unregisterAllFlagsListener('example-2', 'test');

Expected behavior
Updates are still delivered when switching to a non-default environment using registerAllFlagsListener.

SDK version
5.1.0

OS/platform

Hi @gwhelanLD @louis-launchdarkly,

Sorry for the very late reply. I tried it out now with the latest version (6.1.2) and can confirm that the issue is fixed.

Thank you 👍
