Fix FTP example to handle failure to open network session

The example code only dealt with successful opening of the session.
If the session open failed, the application is stuck because the
connect button is disabled.
Moved the session open to be part of connection.
Handled session open failure by puttin the UI back in the default
state where connection button is enabled.
