This is a preparation for electron 14+, where electron-store is no longer
in a usable state (currently used version does not work due to remote module
removed in electron 14, latest version extends every app startup to 10 seconds).
Once sufficient migration period has passed, electron-store and
redux-persist-electron-storage and the ipc call introduced here
(electron-store-exists) can be removed.
the remote module will be removed from electron 14 onwards,
so replace the locale detection with native browser api that
is available in the renderer.
