DetailsLister - failed to make first entries

[ewerybody]

@Cyberklabauter reported some issues on a2#250:

Somehow doesn’t work properly. After first entry I still got the message “There is nothing to popup! Apparently there was no data added yet?” Than it started working. after I checked the box “finished after first selected item”. Pasting the item still fails (I getting an empty popup-menu with “cancel” entry only). Keys and values are not saved. After a while my test entries where gone again.

This module is kinda new. Had some revisions yet but I guess initilizing is rather badly covered?
Surely we need some testing starting off with NO data yet.
Eventually this should have some defaults for the user to play around and overwrite/delete then.

Ok. I found the issue: I was recently adding another piece of data to the table-data, so I needed to move it up a level to have the new checkbox value and the table data side by side in the saved user data. And I forgot to sanitise the lookup 🤦‍♀️

While I was at it: I rolled it back to using clipboard_paste (using WinClip) works like a charm :) 👍
