Fixes to changeset c8369de328be (made log headless). - Use the correct type when calling BUNfnd; - Don't use BUNinplace if the BUN being changed was committed: it is   then not "headless" anymore; - Don't call BUNinplace with incorrect "head" value, but rather use   NULL to indicate that the value isn't used.
