3f89e1eb23 Prevent processing duplicate payment requests (João Barbosa)

Pull request description:

  Considering the following from Qt [src/plugins/platforms/cocoa/qcocoaapplicationdelegate.mm#L267](13e0a36626/src/plugins/platforms/cocoa/qcocoaapplicationdelegate.mm (L267))

  ```cpp
  - (void)application:(NSApplication *)sender openFiles:(NSArray *)filenames
  {
      Q_UNUSED(filenames);
      Q_UNUSED(sender);

      for (NSString *fileName in filenames) {
          QString qtFileName = QString::fromNSString(fileName);
          if (inLaunch) {
              // We need to be careful because Cocoa will be nice enough to take
              // command line arguments and send them to us as events. Given the history
              // of Qt Applications, this will result in behavior people don't want, as
              // they might be doing the opening themselves with the command line parsing.
              if (qApp->arguments().contains(qtFileName))
                  continue;
          }
          QWindowSystemInterface::handleFileOpenEvent(qtFileName);
      }
  ```

  And that a2714a5c69 was merged, now Qt isn't able to filter out the above notifications, and then a [QFileOpenEvent](https://doc.qt.io/qt-5/qfileopenevent.html) event is delivered to `PaymentServer::eventFilter`, which in turn (re)adds the payment request.

  This change fixes #17025, but makes sense regardless of the issue.
