Good-enough mode is not good enough.

If tv3 data is not correctly formated, we can have a situation where it is impossible to create the first changeset due to a lack of data. In my case I have a comment that has been submitted before the initial changeset (sic).

The current implementation throw an exception in that case, and catch it inside the for loop that creates changeset. This is a problem since if no initial changeset has been created, then subsequent changeset won't be created (this currently leads to a fatal error).

My proposal is to create a fake changeset in that case.
