share: wrap bmstore._writerepo for transaction sensitivity (issue4940)

46dec89fe888 made 'bmstore.write()' transaction sensitive, to restore
original bookmarks correctly at failure of a transaction.

For example, shelve and unshelve imply steps below:

  before 46dec89fe888:
    1. move active bookmark forward at internal rebasing
    2. 'bmstore.write()' writes updated ones into .hg/bookmarks
    3. rollback transaction to remove internal commits
    4. restore updated bookmarks manually

  after 46dec89fe888:
    1. move active bookmark forward at internal rebasing
    2. 'bmstore.write()' doesn't write updated ones into .hg/bookmarks
       (these are written into .hg/bookmarks.pending, if external hook
       is spawn)
    3. rollback transaction to remove internal commits
    4. .hg/bookmarks should be clean, because it isn't changed while
       transaction running: see (2) above

But if shelve or unshelve is executed in the repository created with
"shared bookmarks" ("hg share -B"), this doesn't work as expected,
because:

  - share extension makes 'bmstore.write()' write updated bookmarks
    into .hg/bookmarks of shared source repository regardless of
    transaction activity, and

  - intentional transaction failure at the end of shelve/unshelve
    doesn't restore already updated .hg/bookmarks of shared source

This patch makes share extension wrap 'bmstore._writerepo()' instead
of 'bmstore.write()', because the former is used to actually write
bookmark changes out.
