Instance extras are stored as serialized objects in the database and
because of this it is possible to get a version back that is older
than what the client requested. This is in itself not a problem, but
the way we do things right now in conductor we end up trying to
backport to a newer version, which raises InvalidTargetVersion.
This change adds a check to make sure we skip backporting if the
requested version is newer than the actual db version as long as the
major version is the same.
