Fix error in tree iterator when popping up trees There was an error in the tree iterator where it would delete two tree levels instead of just one when popping up a tree level. Unfortunately the test data for the tree iterator did not have any deep trees with subtrees in the middle of the tree items, so this problem went unnoticed. This contains the 1-line fix plus new test data and tests that reveal the issue.
