revpair: smartset compatibility

Since recent revset changes, revrange now return a smartset. This smart set
probably does not support indexing (_addset does not). This led to crash.
Instead when the smartset is ordered we use the `min` and `max` method of
smart set. Otherwise we turn is into a list and use indexing on it.

The tests have been updated to catch such regression.
