[PATCH] comctl32: LVM_INSERTITEM handler should send the LVN_ITEMCHANGING/LVN_ITEMCHANGED notifications.

[Nikolay Sivov]

The test is not adequate for the change you're making. Just one example, 
inserting with just LVIF_PARAM set now produces incomplete 
(LVN_ITEMCHANGING, LVN_INSERTITEM), I don't see the same on Windows.
