ui: extract buffer write from protect and timed 'write_err' output

That subcall to 'self.write' is never doing actual write but only store things
in buffers. So we do not need to protect it for exception not to time its
execution.

This will make it easier to extract a '_write_err' function as we did for
'write'.

  $ hg init
  $ echo This is file a1 > a
  $ echo This is file b1 > b
  $ hg add a b
  $ hg commit -m "commit #0"
  $ echo This is file b22 > b
  $ hg commit -m "comment #1"
  $ hg update 0
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ rm b
  $ hg commit -A -m "comment #2"
  removing b
  created new head
  $ hg update 1
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ rm b
  $ hg update -c 2
  abort: uncommitted changes
  [255]
  $ hg revert b
  $ hg update -c 2
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ mv a c

Should abort:

  $ hg update 1
  abort: uncommitted changes
  (commit or update --clean to discard changes)
  [255]
  $ mv c a

Should succeed:

  $ hg update 1
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
