localrepo: make _refreshfilecachestats unfiltered method to refresh correctly

Before this patch, if transaction is started via "filtered repo"
object, _refreshfilecachestats() at closing transaction doesn't
refresh file stat of any @filecache properties correctly, because:

  - _refreshfilecachestats() omits refreshing file stat of a
    @filecache property, if it doesn't appear in self.__dict__

  - if transaction is started via "filtered repo",
    _refreshfilecachestats() is applied on "filtered repo"

    because repo.transaction() adds "self._refreshfilecachestats" to
    post close procedures. repo.transaction() isn't unfiltered method,
    and "self" in it means "filtered repo" in this case.

    Transactions started by explicit repo.transaction() easily causes
    this situation.

  - _refreshfilecachestats() applied on "filtered repo" omits whole
    refreshing

    because @filecache properties are stored into "unfiltered repo",
    and appear only in self.__dict__ of "unfiltered repo".

This incorrect refreshing causes unnecessary reloading from files.

To refresh file stat of @filecache properties at closing transaction
correctly, this patch makes _refreshfilecachestats() unfiltered
method.

This patch chooses making _refreshfilecachestats() unfiltered method
instead of making transaction() unfiltered method, to reduce
unexpected side effect.

(Translations are optional)

#if gettext no-outer-repo

Test that translations are compiled and installed correctly.

Default encoding in tests is "ascii" and the translation is encoded
using the "replace" error handler:

  $ LANGUAGE=pt_BR hg tip
  abortado: n?o foi encontrado um reposit?rio em '$TESTTMP' (.hg n?o encontrado)!
  [255]

Using a more accommodating encoding:

  $ HGENCODING=UTF-8 LANGUAGE=pt_BR hg tip
  abortado: n\xc3\xa3o foi encontrado um reposit\xc3\xb3rio em '$TESTTMP' (.hg n\xc3\xa3o encontrado)! (esc)
  [255]

Different encoding:

  $ HGENCODING=Latin-1 LANGUAGE=pt_BR hg tip
  abortado: n\xe3o foi encontrado um reposit\xf3rio em '$TESTTMP' (.hg n\xe3o encontrado)! (esc)
  [255]

#endif
