Merge lp:~cjwatson/launchpad/db-git-no-target-implies-owner into lp:launchpad/db-devel

[Colin Watson]

Drop GitRepository.target_implies_owner constraint.

GitRepository.target_default implying GitRepository.owner_default has some difficult-to-resolve consequences for permissions, since the target owner might legitimately not be the repository owner and thus might not be able to set the owner-target default. We agreed in the Launchpad team meeting last night to remove this restriction, so we need to drop the constraint that enforces it.
