repo: repo isolation, do not pass on repo.ui for creating new repos

A repo should not get the configuration from an other repo, so create it with
the global configuration in repo.baseui.
This is done too when recreating a repo. The repo configuration is reread
anyway. And now deleted repo configuration does not persist.
