Resolve emscripten problem with save as during close by queued connection.
It seems that directly connected one dialog result signal to method which created another modal dialog results in new dialog to be hidden when finished dialog closes under emscripten. Queued connection resolves this problem for simple case of source file close. It still does not resolve save as invocation during complete application close.
