fix(canvas) Better Remix Reset Handling.

- Removed handling of reset triggering from `editorDispatchClosingOut`.
- Added `useRouteError` wrapper to `createBuiltInDependenciesList`.
- `reactRouterErrorTriggeredReset` now returns a `RESET_CANVAS` action as
  required.
- Incoming updates from the code editor can now trigger the canvas reset.
