I don't understand how to use "URI safe" name, something like
```localHostNameURISafe``` or what?
It's good to format URIs only in places where we need it, but currently we
have more than one bug because of it.
However we can use something like
```InetAddresses.toUriString(InetAddress.getByName(Utils.localHostName()))```
to get URI in place without fixing Utils module, but i think that special URI
method may prevent URI-based bugs in future due to its existence.
