The global variable tinyMCE has an array of editors. So you have to call the undoManager inside them. Like this for default wp editor on post edit/create screen:
tinyMCE.editors[0].undoManager.clear();
If you want to do it in a specific editor, select the editor id in n like this:
var n = 0; // editor id
tinyMCE.editors[n].undoManager.clear();
