Make CloseWarningDialog async (#8117)

Browse source 
The CloseWarningDialog is now "awaitable"/async, as suggested in PR #7871.

As opening the dialog is async, the flag can be reset in the same
method. This way the flag operations occur in the same method.  The
event handlers of the buttons became obsolete and are removed.

## Validation Steps Performed
Tested manually.
