Document that wxTreeCtrl::DeleteChildren() does send events

Browse Source 
Contrary to what the documentation stated previously, this function does
generate the wxEVT_TREE_DELETE_ITEM events for all the items being
deleted, in both MSW and generic implementations.

Update the documentation and add a new unit test checking that the
behaviour really conforms to it.
