[boskid][2.0.28] Upgrade planner does not upgrade blueprint icon's quality symbol

[sOvr9000]

Make a blueprint. Set its icon to an entity with any quality. Make an upgrade planner to upgrade that entity's quality to another quality. Upgrade the blueprint with the upgrade planner. The quality of the entity in the icon does not get upgraded, but any entities in the blueprint do correctly get upgraded.

This behavior is inconsistent with the fact that blueprint icons get upgraded when the upgrade happens between two different types of items, like from a blue belt to a green belt.
