Eliminate remaining Electron 8 deprecations

* Change systemPreferences.isDarkMode() to nativeTheme.shouldUseDarkColors

* Remove vibrancy parameter to BrowserWindow

* Update curve25519-n; removes context-aware deprecation warning

* Set app.allowRendererProcessReuse = true to remove warning

* Move from deprecated setters to direct property set

* Serialized sender certificates: Store less, store plain object

* isMenuBarAutoHide -> autoHideMenuBar

* UUID: Fix sealed sender indicator on message details screen

* Data._cleanData: Remove function keys, handle null in array

Also:
- run _cleanData when saving attachment download jobs
- remove job from jobs table when the send itself throws error

* _cleanData: Don't dig into strings, booleans, or numbers

* getPropsForMessageDetail: Make it clear what we're reducing
