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

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