topic: properly decode topic and topic namespace after reading from disk

Looks like we forgot that the bytes read from disk should be converted to the
local encoding. The way it's done in this patch is how branch is handled in
core.

evolve --rev reorders the rev to solve instability, trivial case 2 revs wrong order

evolve --rev reorders the rev to solve instability. Harder case, obsolescence
accross three stacks in growing rev numbers.

Evolve --rev more complex case: two sets of stacks one with prune an no successor, the other one
partially solvable
 
First set of stack:
  $ mkstack "desc(_d)" c1_ c2_ c3_ c4_ >/dev/null
  $ mkstack "desc(_d)" c1prime c2prime >/dev/null

  1 changesets pruned
  $ hg prune "desc(c1prime)" -s "desc(c1second)"
  1 changesets pruned
  1 new orphan changesets
