Allow successful import, without confirmation dialog acceptance

[Alexander Renfert]

Currently, if the confirmation box is not clicked, after an import has finished, the platform will not appear and the games will not show as if they exist, until doing so. This occurs if the platform import had errors OR does not have errors.

The problem is when an import takes multiple hours, and even though the import has successfully finished, it is possible that the confirmation box was never closed. For example, if a Windows Update triggers a reboot (after the confirmation dialog has appeared), the platform and games will not show up as being imported. However, when managing the platforms, you'll see that the platform exists.

Setting this to bug for now, since I can understand why this can occur if a user did not accept the import that contains error, but not on an otherwise successful import.
