/ge collect for beds does not work - beds get converted into air

[Tophattingson]

Describe the bug Repeat of https://github.com/The-Fireplace-Minecraft-Mods/Grand-Exchange/issues/18 but I can add information about what it does to the exchange database.

To Reproduce Steps to reproduce the behavior:

1. Create an offer to sell a bed.
2. Cancel the offer.
3. Attempt to collect the bed.
4. "You have run out of room for collection. Make room in your inventory and try again."

Logs/Screenshots/Videos The data present in the exchange database all but confirms the cause of this error. It appears that beds get converted into the air block when waiting for collection. As you cannot hold an air block, this presents an obvious error when you try to collect it.
