Closing the editor after losing connection to perforce will cancel the save and discard changes

If a project loses connection to perforce and is then closed, the editor will prompt to save changes. If any of those changes require checking out an asset, the editor will prompt to check out the asset. This checkout will fail and the editor will immediately close without successfully saving causing the loss of work.

1. Connect to Perforce
2. Open a project that is connected to Perforce
3. Open and edit a blueprint that is part of the Perforce repo
4. Close Perforce
5. Use the "X" to close the editor

Result:
Prompted to checkout/save asset however the checkout fails and the editor closes without saving.

Expected:
If the checkout/save fails, editor remains open until closed agaiin
