blackbox: do not assume self._bb{vfs,repo,fp} are set in blackboxui.__init__

It's possible for the blackboxui code to do a "del self._bbvfs", then ui.copy()
or similar attempt will fail. It will also fail when constructing a blackboxui
from a non-blackbox ui.
This patch fixes the issue by not assuming any _bb* attr is set.

  $ hg init
  $ echo This is file a1 > a
  $ hg add a
  $ hg commit -m "commit #0"
  $ echo This is file b1 > b
  $ hg add b
  $ hg commit -m "commit #1"
  $ hg update 0
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ echo This is file c1 > c
  $ hg add c
  $ hg commit -m "commit #2"
  created new head
  $ hg merge 1
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ rm b
  $ echo This is file c22 > c

Test hg behaves when committing with a missing file added by a merge

  $ hg commit -m "commit #3"
  abort: cannot commit merge with missing files
