Sylius: CoreBundle/Resources/config/services/form.xml references a non existent class

[pfazzi]

Sylius version affected: 1.6.2

Description
CoreBundle/Resources/config/services/form.xml contains a definition of a service with a non existent class:
https://github.com/Sylius/Sylius/blob/a12ce58e9ebce9b465fe8869110bafdd2934e30f/src/Sylius/Bundle/CoreBundle/Resources/config/services/form.xml#L180

Possible Solution
Remove service config.

Edit:
I found 3 bad service definitions:

1. sylius.form.event_subscriber.build_promotion_rule
2. sylius.form.event_subscriber.build_promotion_action
3. sylius.form.type.data_transformer.product_variants_to_codes
