Subject: [mount-store] Take greater care where the .notmounted flag is written

While the task manager should make sure only one invocation if
mount-store is running, add a few extra checks whether a mount-point is
pulled under our feet, or mounted when we don't expect it.
This includes making sure dmsd is not accessing the share while we're
trying to manipulate it.
