macOS: activate correct object when using multiple QSystemTrayIcons

Since we need to set the delegate on the defaultUserNotificationCenter,
which is a gobal object, we have to update the delegate when we show
the message. Otherwise, the last delegate created and set will receive
the notification, and the last QSystemTrayIcon created will emit the
activated signal.

Before clearing the delegate upon destruction, make sure that it's
the right item first.

Also updating coding style in the respective parts of the code, and
plugging a memory leak.
