  Changed paths:
    M src/director/director-connection.c

  Log Message:
  -----------
  director: Avoid a potential assert-crash after removing a director from ring.

This should fix the crash:
Panic: director: file director-connection.c: line 1926 (director_connection_init_out): assertion failed: (!host->removed)

Also moved the last_network_failure timestamp reset a bit later, since
there's no need to reset the timestamp if we're not actually connecting
to the server.
