repositories: allow updating repository settings for users without store-in-root permissions...
repositories: allow updating repository settings for users without store-in-root permissions in case repository name didn't change. - when an user owns repository in root location, and isn't allow to create repositories in root before we failed to allow this user to update such repository settings due to this validation. We'll now check if name didn't change and in this case allow to update since this doesn't store any new data in root location.
