Initial task parameters are being included in task log of info

[Rahlir]

With the release of taskwarrior 3.3, we got back the task log feature, awesome, thanks for that! However, I noticed that the log now includes the initial values of task parameters. This is different from how it was previously (which in of itself doesn't have to be a bad thing) and I think it also doesn't really make sense: after all the point of the log is to show changes. One can easily infer the initial values by inspecting the changes and comparing them to the current value. Moreover, this log can take up a lot of screen estate if you have large amount of UDAs (which is usually the case for tasks imported via bugwarrior).

Hence, would it be possible to go back to showing only changes to the task in the task info log? Is there a technical reason for this new behavior? I know that taskwarrior moved to sqlite in the 3.x version, so perhaps that has something to do with this new behavior.

If it is technically feasible, I could also have a go at implementing this "fix" myself if @djmitche is stretched for time. I haven't had a look at the new task info implementation, but I am somewhat familiar with the previous version of the code-base.
