blackbox: properly replace ui class

Without this, anyone creating a ui object using: uimod.ui()
skips the blackbox.

Also, anyone doing ui.copy() skipped the blackbox.

Unfortunately, the ui object lifestyle is a bit messy,
the first one that's created is never actually initialized
with subclasses, instead pieces of the subclass are adopted
into the primal ui object. In order to handle this, a
_partialinit method will be called to ensure that the
blackboxui is properly initialized.

  $ hg init
  $ echo This is file a1 > a
  $ hg add a
  $ hg commit -m "commit #0"
  $ ls
  a
  $ echo This is file b1 > b
  $ hg add b
  $ hg commit -m "commit #1"
  $ hg co 0
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved

B should disappear

  $ ls
  a
