Missing schema definitions

Problem/Motivation

We have kernel tests that enable geolocation,geolocation_google_maps and geolocation_address modules. The test results in the following errors:

Drupal\Core\Config\Schema\SchemaIncompleteException: 
Schema errors for core.entity_view_display.node.event.default with the following errors:
