Spawn eggs when have empty entity value (Example:383:87) have a glitchy icon in inventory and have a name of Spawn .name>

*What I expected to happen was that it would come up with just Spawn as the name and the icon to be the blank spawn egg icon from pc.

*What actually happened was the name was Spawn .name> and it's icon is just from the items.png file

Steps to Reproduce:
1. Spawn in a spawn egg in survival
2. Edit the spawn eggs damage value
3. Open Minecraft on that world
