Electron: Use-after-free in download save dialog callback

Details

### Impact Apps that allow downloads and programmatically destroy sessions may be vulnerable to a use-after-free. If a session is torn down while a native save-file dialog is open for a download, dismissing the dialog dereferences freed memory, which may lead to a crash or memory corruption.

Apps that do not destroy sessions at runtime, or that do not permit downloads, are not affected.

### Workarounds Avoid destroying sessions while a download save dialog may be open. Cancel pending downloads before session teardown.

### Fixed Versions * `41.0.0-beta.7` * `40.7.0` * `39.8.0` * `38.8.6`
