Bugfix: In the past two releases, git-annex init has written the uuid.log in the wrong format, with the UUID and description flipped.

This is my own damn fault for not making UUID a real type, and then relying
on the type checker to ensure my refactoring was correct -- which it wasn't!

I should probably add code to clean up bogus entries in the uuid.log, but
right now I want to get the fix out there to prevent people experiencing
this bug.

I should also make UUID a real data type.
