undo-files: cleanup backup when cleaning undos

Previously, the backups were left behind, by operation cleaning the undo's like
strip, narrow and stream clone.

The remaining elevant in the room is the transaction itself, who does not
properly cleanup undo backup before copying the new ones.

  $ rm -rf a
  $ hg init a
  $ cd a
  $ echo a > a
  $ hg ci -Am0
  adding a
  $ hg tag t1 # 1
  $ hg tag --remove t1 # 2

  $ hg co 1
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg tag -f -r0 t1
  $ hg tags
  tip                                3:a49829c4fc11
  t1                                 0:f7b1eb17ad24

Ensure that the username access fails gracefully if assumptions about the
environment made by python do not hold.
