bundlerepo: disable filtering of changelog while constructing revision text

This avoids the following error that happened if base revision of bundle file
was hidden. bundlerevlog needs it to construct revision texts from bundle
content as revlog.revision() does.

  File "mercurial/context.py", line 485, in _changeset
    return self._repo.changelog.read(self.rev())
  File "mercurial/changelog.py", line 319, in read
    text = self.revision(node)
  File "mercurial/bundlerepo.py", line 124, in revision
    text = self.baserevision(iterrev)
  File "mercurial/bundlerepo.py", line 160, in baserevision
    return changelog.changelog.revision(self, nodeorrev)

    node = self.node(rev)
