Bug - Tree Grid - EnableCollapseAll set to true throws a NullReferenceException

[Lee Stevens]

When EnableCollapseAll is set to true on an SfTreeGrid, a null reference exception is thrown after the page is rendered

If you call Grid.CollapseAllAsync from code behind, the same exception is thrown

Sample attached to replicate the issue. If you set EnableCollapseAll to false the control loads correctly.
