subrepo: replace "os.path.exists" by "exists" via wvfs of the parent

Existance of specified "path" should be examined by "exists" via wvfs
of the parent repository, because the working directory of the parent
repository may be in UTF-8 mode. Wide API should be used via wvfs in
such case.

In this patch, "/" is used as the path separator, even though "path"
uses platform specific path separator (e.g. "\\" on Windows). But it
is reasonable enough, because "store" and other management file
handling already include such implementation, and they work well.

  $ hg init foo
  $ cd foo
  $ echo foo > foo
  $ hg add foo

mq may keep a reference to the repository so __del__ will not be
called and .hg/journal.dirstate will not be deleted:

  $ hg ci -m foo
  error: pretxncommit.nocommits hook failed: no commits allowed
  transaction abort!
  rollback completed
  abort: no commits allowed
  [255]
  $ hg ci -m foo
  error: pretxncommit.nocommits hook failed: no commits allowed
  transaction abort!
  rollback completed
  abort: no commits allowed
  [255]

  $ cd ..
