Fix build

Unfortunately, due to bugs in Electron 9, we can't use devtron (electron/electron#23676). We could at least get Ember Inspector to load (using the workaround for electron/electron#23656), but hopefully Electron will turn around a quick fix at least for that second issue so we don't have to add a temporary workaround to the blueprint-generated code...
