Fix: crash on crafting certain quirky items

[Nostrademous]

Fixes #5109

Description of the problem being solved:

The short-cut to strip a repeat of the base name of an item appear as a modifier when copy/pasting from trade website was incorrectly implemented to short-circuit entry into the subsequent if block by setting specName to a value.

This caused certain parameters of quirky items like a Fishing Rod, Timeless Jewel or Ring of subtype Ring (basically any item with a subType equal to the main base item Type) to not be properly initalized.

Steps taken to verify a working solution:

• Verified creation of all items reported in Issue Error when trying to add a timeless jewel base / ring / fishing rod #5109 without error
• Verified that copy/paste from PoE Tradesite does not treat the subType of the item as a modifier.

Just make any build and Item -> Craft item... OR Create Custom...
