Views are created with the wrong view creator

• At a merge, the merge leader creates a view in which the ViewId.creator is not itself.
• This opens the possibility that two different nodes might simultaneously be creating different views - but with the same ViewId
• This is bound to lead to confusion, if it happens

This is per pull request 54, which contains further discussion and a proposed fix.

(I'm raising this ticket just to have everything tracked in one place).
