Bug with UCD data "BadZipFile" on first run

[belluzj]

It only happens when running the first time, then when running again it's fine, so maybe some timing issue, not waiting until the end of some download? And not blocking, since it's enough to restart the run. Here is the stacktrace:

@simoncozens seems to be occurring due to youseedee

[simoncozens]

Yeah, looks like it but I can't repro. :-/ @belluzj Could you

a) Clean out your ~/.youseedee folder and try again?
b) If it fails again, inspect ~/.youseedee/UCD.zip.

[RickyDaMa]

To fix this in diffenator2, the youdeesee dependency needs to be updated to at least v0.5.0 (from ^0.3.0)

Unfortunately, trying this locally meant all the functional tests failed. Not sure if that's my environment or not, but it wasn't exactly encouraging :(

[m4rc1e]

@RickyDaMa I just updated youseedee to 0.5.0 and deleted ~/.youseedee and all checks pass (I'm on OS X).

Lemme open a PR and see what our win ci makes of it.
