#167 Telnet restart does not work

[Jean-Baptiste REICH]

When I try to restart the console telnet bundle (version 3.0.1) I got the following error and the telnet server is no longer available

> stop 19
Stopped: Telnet-Console-IMPL (#19)
> start 19
Started: Telnet-Console-IMPL (#19)

[Jan Stein]

The problem is a dangling server socket that isn't fully closed. We should add code to self connect during shutdown.
