Stealthy onions should appear to be offline

Working on legacy/trac#27680 (moved) and testing basic and stealth onion services i noticed that they behavior is the same. Instead i expected the stealthy one to look like it's offline. See also legacy/trac#23653 (moved)

What i observed was for both auth types (without correct auth cookie in the client):

When the descriptors weren't uploaded yet, the client failed immediately:

[warn] {REND} Fetching v2 rendezvous descriptor failed. Retrying at another directory.                                                                       
{REND} Closing stream for '<scrubbed>.onion': hidden service is unavailable (try again later).

After uploading the descriptors the connection timed out:

[notice] Tried for 120 seconds to get a connection to <scrubbed>:80. Giving up. (waiting for rendezvous desc)

Please let stealthy onions appear to be offline.
