#4051: The `tor_introducer` fixture should wait for the `tor_network` fixture

 `tor_network` uses chutney to set up a local Tor network for the
 integration tests.  `tor_introducer` creates an introducer node that
 should be reachable over Tor, using the local Tor network.

 Since `tor_introducer` has no dependency on `tor_network`, nothing
 guarantees pytest will create the Tor network before it tries (and fails)
 to create the Tor-using introducer node.

 Maybe this is why the Tor integration tests seem to randomly fail.
