    smart transport: only clear url on hard reset

After creating a transport for a server, we expect to be able to call
`connect`, then invoke subsequent `action` calls.  We provide the URL to
these `action` calls, although our built-in transports happen to ignore
it since they've already parsed it into an internal format that they
intend to use (`gitno_connection_data`).

In ca2eb4608243162a13c427e74526b6422d5a6659, we began clearing the URL
field after a connection, meaning that subsequent calls to transport
`action` callbacks would get a NULL URL, which went undetected since the
builtin transports ignore the URL when they're already connected
(instead of re-parsing it into an internal format).

Downstream custom transport implementations (eg, LibGit2Sharp) did
notice this change, however.

Since `reset_stream` is called even when we're not closing the
subtransport, update to only clear the URL when we're closing the
subtransport.  This ensures that `action` calls will get the correct URL
information even after a connection.
