Yuya Nishihara ae62b5b946 repo: teach OpStore about the root commit id
This removes an invalid View state from the root operation.

Note that the root index will have to be reindexed in order to resolve "root()"
in the root operation. I don't think this would practically matter, so this
patch doesn't bump the index version to invalidate the existing indexes.

See also 48a9f9ef56 "repo: use Transaction for creating repo-init operation."
