Vadim Zeitlin 9fee931d6d Work around a crash in wxGTK3 GUI test suite
The tests crashed after running ModalDialogsTestCase::FileDialog() because the
next call to wxYield() resulted in the completion of an async operation
launched by the native file dialog which tried to dereference the already
destroyed dialog.
