pm-update fails when there is bzr and more than 1 project to update

Update fails, when using bzr version control, and there is more than one project to update. The reason is because after installing the first project, drush does a bzr status, and sees the uncommitted changes from that first update. It then aborts the rest of the updates, and proceeds to roll back the first one.
