Reconnect operation doesn't re-read connection settings (in particular: On Connect Commands)

[knocte]

Steps to reproduce:

1. Fill "/join #foo" in your "On connect commands" section of some IRC network (e.g. freenode).
2. Connect to freenode network. Wait until it finished connecting.
3. Go to smuxi preferences, edit freenode network settings, remove the "/join #foo" command.
4. Right-click on freenode network: Reconnect.

Current results:
After connecting to freenode again, it still joins #foo channel.

Expected results:
It should not connect to #foo channel because the command was removed.
