Describe the bug
When right clicking onion, it sometimes only provides 1 onion and thus replants itself, so no onions are returned to the inventory. It should yield at least 2 from a fully grown onion (1 to replant, 1 to use)

To Reproduce

1. Go plant onion
2. Let it grow to full
3. Right click to farm
4. See it re-plant but no additional onion in inventory

This intermittent, sometimes it does yield 2 onions like it should, but not guaranteed.

Expected behavior
At least one onion returns to inventory and one onion is planted.

Screenshots

Additional context
This is being used inside the FTB Omnia Modpack

Environment

• Minecraft Version: 1.15.2
• XL Food Mod Version: 2.2.2
• Forge Version: 31.2.31

This is technically not a bug on my end as my mod doesn't have right click harvesting yet but it should be fixed when I re-add it back into my mod. Soon.

Onion seeds are missing for version 1.12.2 and older versions as well. Would you be able to add them in?
