Tree Component 3.2.4 breaks tests

[michaelkleinhenz]

With the above version, the WI list in inmemory does not display any list entries. There is no error on the console, it just fails silently, not displaying any cells. The DOM does not contain the entry cells. Looks like the component just does not recognize entries in the data model.

Same source works on prod(!). Downgrading to 3.2.3 also makes it work again.

This is a bit of urgent, we can now choose to either break tests or prod. :-(

This looks like the upstream issue: CirclonGroup/angular-tree-component#239
At least it looks very similar.
