Server fails to respond to Hello message if there aren't bulletins in the Db

[vinloren]

I cloned the repository to my Windows PC and configured my installation with no problem but as I tried it sending Hello message to the device connected to the BBS I got the following error:

"D:\TC2-BBS-mesh-NA\message_processing.py", line 137, in process_message
handlers[message_lower](sender_id, interface)
File "D:\TC2-BBS-mesh-NA\command_handlers.py", line 85, in handle_bulletin_command
response = f"📰Bulletin Menu📰\nSelect the board to enter?\n[G]eneral (" + datum(date[0]) + ")\n"
~~~~^^^
TypeError: 'NoneType' object is not subscriptable

I eventually discovered that the cause of this bug is due to the application non handling the case of bullettin table empty which produces a None result. I then wrote a fake bulletin using Sqlite3 DB Browser and the access to the BBS via Hello or B message was solved. The problem however showed up again when I tried to access the B (bulletin) menu since also for Info, News, and Urgent boards the application does not handle the case of None result. I then inserted a fake bulletin viaDB Browser for each different board and after that th Bulletin menu did work fine.

I think correcting this issue is necessary to avoid possible disaffection of users to this remarkable project.

P.S: I'd like to highlight the fact that above bug was found on the ReneKlever forked version and actually I wanted to address the issue to him but unfortunately while signalling the issue I dropped here.. This problem did not occur on the original TC2-BBS version whatsoever. Sorry for the inconvenience but I could not address Rene Klever on his repository.
