Title: Allow logged in users to update a slice *so long as there is no owner*

As a logged in user, often I'm working alone on my own cakes. Sometimes I'll forget to claim a slice, and try to update it, which fails - asking me to take ownership.

Instead of failing and hassling me, I'd suggest allowing the edit - so long as no one else owns the slice.
