remove workaround for old bug that was only in one release

It's causing some problem on windows, see
http://git-annex.branchable.com/bugs/windows_port_-_repo_can__39__t_pull_newly_added_files_/#comment-45df9748bba687d95e3c96b3877ea925
And only affected WORM backend, and for one release well over a year ago,
so could well be bitrotted.
