EvMenu custom exit node runs cmd_on_exit twice

Brief summary of issue / Description of requested feature:

On Evennia 0.6 at least, using a custom exit node runs cmd_on_exit twice.

Steps to reproduce the issue / Reasons for adding feature:

Load the following code into @py/edit and execute.

from evennia.utils.evmenu import EvMenu

def start(caller):
    return "Hello world!", {"desc": "Custom exit node", "goto": "exit"}

def exit(caller):
    return None, None

EvMenu(self, {"start": start, "exit": exit}, startnode="start")

Error output / Expected result of feature

Two look commands are run by the character. This does not occur if you use the default quit command.

Extra information, such as Evennia revision/repo/branch, operating system and ideas for how to solve / implement:

My guess is that close_menu() is being hit twice, possibly in evtable_parse_input and EvMenu.goto.

I’ll dibs this. It’s probably an unexpected result of the last PR I did on EvMenu. Previously single node EvMenus would bug out. It treats the first node differently to the rest of the nodes and didn’t expect an EvMenu to end on the first node. I suspect my solution to that problem is running close_menu() twice resulting in the doubling up of the cmd_on_exit. It should be a simple fix.

I do. The above code replicates it for me. I am definitely on the latest evennia.
