Steps to Reproduce:

1. Build this sample extension (test-provider-sample) - https://github.com/r3m0t/vscode-extension-samples/tree/test-sort-error-fix
2. Press 'refresh' in Testing panel repeatedly. Expected: the 'error' message should update and the 'Order' children should switch order. Actual: the children get updated labels, but still rendered in the old order. And the 'error' message doesn't update.
