Memory leaks when expanding

[chelentos]

Problem

When expanding and hiding tree nodes, number of nodes and size of js heap only grows.

Reporduction

Can be reproduced on base example in storybook: https://preview.gravity-ui.com/table/?path=/story/basetable--tree or https://preview.gravity-ui.com/table/?path=/story/table--tree

js heap manages to be cleaned, but nodes counter only grows
