CONFIRM_OVERWRITE_TRANSMOG_OUTFIT dialog calls missing SaveOutfit method

[Meorawr]

The CONFIRM_OVERWRITE_TRANSMOG_OUTFIT static popup dialog calls WardrobeOutfitFrame:SaveOutfit in its OnAccept handler, which is a method that doesn't exist.

To reproduce the issue, at a transmogrification NPC create a new outfit with the name "Test", and then create a second outfit with the same name. When prompted if you want to overwrite it, click "Yes".
