Duplicated messages in testdata appeared because default renderer
renders diagnostic spans ambiguously. It shows only start position.
In fact, there are 3 failures, 2 of them distinguish only by the
diagnostic end offset. See youtrack for more information.
The issue about inconvenient rendering is KT-64989.
