tests: workarounds to keep treeview scrolling tests running

Browse Source 
We can't safely examine allocations synchronously using
gtk_main_iteration(), as there might be not enough time for a new paint
clock tick to have expired and the allocation set on the widget.
Work this around adding g_usleep() calls before processing pending
mainloop events.
