[Devtools] Fix network grouping experiment

There was a regression recently that was fixed (https://codereview.chromium.org/2838673003/) but broke the network grouping experiment. This patch fixes that regression.

We were deeming the item as not needing to be removed or added without checking if there is a new parent.
