PATCH - Avoid removing listbox item with (-1) index.

[Oleg Prokhorov]

Hello wine-patch,

Problem:
I've found that wine allows to remove items form combobox/listbox with
invalid (-1) index /item is not selected/. Windows doesn't allow this.

Change-log:
Avoid removing listbox item with (-1) index.
