Some users have their log full of these errors:
2019-01-10 18:14:47 17494 123145559568384 ERROR nxdrive.engine.watcher.remote_watcher Network error: Could not find a suitable TLS CA certificate bundle, invalid path: 1
No request can go through, without any explicit warning for the user.
This seems to come from this line which retrieves the SSL/certificate configuration from the sqlite database. It does not cast the value as a boolean, so we pass "1" or "0" as strings and it breaks the request.
