Add option to leave the "Description" field empty

Hi,

I’m using Lunch Flow to sync my accounts to YNAB. One thing I noticed is that there’s no way to leave the Description field empty. The bank connection doesn’t report any additional information that I would like to import to YNAB, I would just like to leave it empty.

However it seems like the auto fallback mechanism doesn’t let me to do that, even with custom templating. If I put an empty string (`””`) into the template, the fallback is activated and the default description will be added. If I choose a field that the bank returns empty, the string null will be imported into YNAB.

The best I could come up with is to put a whitespace character (`” “`) into the template, but I would prefer if I had an option to just simply leave it empty.

Thanks!
