peer-or-repo: make sure object in "scheme" have a `instance` object
The previous form of having heterogeneous object in the dictionnary makes things
more complicated than they needed to be. I am not super happy about the current
(especially around 'islocal', that most item do not have), but this is already
much better.

Change in middle of the stack (linear commits)
$ hg branch -r 1::3 foo

$ hg branch -r 4 --hidden foobar
