'My Edits' view should display all nodes edited

This is an important change.

Currently 'My Edits' only shows you your edit if you were the last one to have edited the node. If you create a draft and then someone else edits your draft, you will then be in a situation where you have no way of finding that node anywhere in workbench. That's a huge usability problem.

With this change you now see every edit you've made regardless of whether someone else more recently edited it.

This problem may have been introduced by a change in Views and not be the originally intended behavior of Workbench. https://www.drupal.org/node/1754354#comment-9962451 was useful in fixing it.
