macOS build broken if enabling push notifications

Since 95f823f mac builds are broken when enabling push notifications.

To repro:

  • Change the DemoRunner Projucer project under Xcode (macOS) / Push Notification Capability => Enabled
  • Try to build the DemoRunner

I get the following error:

modules/juce_events/native/ Use of undeclared identifier 'didReceiveRemoteNotification'

Sorry about that, this should be fixed here:

Works now! thx
