Only save truthy values in entity_usage.settings for sequences

Problem/Motivation

The entity_usage.settings configuration saves all the available options, even when the options are not checked. This has two negative effects:

• The entity_usage.settings are changed when no new options have been selected, when a new entity type was added since entity_usage.settings was last saved.
• The resulting entity_usage.settings yml file is harder to read

Proposed resolution

Only save truthy values in entity_usage.settings. Compare and contrast the following configuration files:
