ENIGMA crashes if NUA does not collect complete info.

[chilledtonic]

Describe the Bug My understanding was that this pr made collecting full user information unnecessary; however, if you later open the user config page after having some of these values unset (on my board, I do not collect real name or location), and try to tab past an empty line in the config, the board will hard crash with this error.

enigma-bbs/core/text_view.js:156
        text = text.toString();  

To Reproduce

1. Establish a board where NUA does not collect name or location (or skip any default field)
2. Try to edit the account

Expected Behavior

I would prefer either ENIGMA more gracefully handled the empty string.

Actual Behavior

Server crashes completely.

Screenshots If applicable, add screenshots to help explain your problem.

Environment

• [X] I am using Node.js v14.x LTS or higher
• [x] npm install or yarn reports success

@chilledtonic thanks for the report & PR! I should be able to take a look this week.

Can reproduce on a fresh installation of 0.0.14-beta on a RPi. Going through the application form crashes Enigma on using Tab or Enter. This is the feedback on the console:

        text = text.toString();
                    ^

Thanks for the report - we have a open ticket on this right now. I've been super busy, but I'll try to pull that in today and get it to master.

Just pushed the fixes to this -- note that you will need to change your menu.hjson entries and art files for the NUA and CONF so the fields aren't used!
