[GNC] Build ID: 3.3+ (2018-09-29) can't unvoid transactions

[Gene Selkov]

Hello,

After a botched csv import, I have a bunch of empty transactions that are
marked read-only. I can't delete them; the explanation is that they have
been voided. I tried the Unvoid Transaction menu on one of them, with
no success. It did nothing.

I guess I could export the database as sqlite, track down and delete those
transactions, then re-import the remainder, but that appears to be a
tedious job, given the way splits are laid out in the db. Is there an
easier way to do that?

Thank you,
