Relisting items from market: remove all items first, then request inventory

[xPaw]

Currently for every item, it removes the item, and then gets the inventory after a random delay. This is inefficient. A way to fix this would be remove all the items first, then request the inventory once.

This was previously done, but the ids were at some point no longer the same after delisting from market.

I thought the code looks for the same item by id in inventory, did I misread? Otherwise this would be unreliable and could end up listing a new item that wasn't removed from market?

EDIT: I see it's checking by hash name.
