update @ProtonMail web clients: ensure "encrypted search" unavailability

* Enabling @ProtonMail's "encrypted search" feature in the app doesn't make sense since the app goes with in-memory only browser storages (including "indexedDb" storage). So the app will start with a clean in-browser storages on every start.
* The app comes with its own full-text search capabilities, see "local store" point in https://github.com/vladimiry/ElectronMail/wiki/FAQ. The app also supports the code-based search which allows unlimited messages scanning capabilities, see #257.
