refactor: privacy methods added

- methods `changeDatabasePassword` and `getLinkPreviewWhitelist` added
to `privacy.nim`
- `hashPassword` moved to `utils.nim` since it's used from multiple paces
- `getEthAccounts` added to `eth.nim`
- `verifyAccountPassword` method updated so it returns `RpcResponse` now
