SchemaIncompleteException on running tests.

Noticed that while running the functional test, there's a SchemaIncompleteException indicating some missing schema errors for the easy_breadcrumb.settings configuration.
Drupal\Core\Config\Schema\SchemaIncompleteException: Schema errors for easy_breadcrumb.settings with the following errors: easy_breadcrumb.settings:remove_repeated_segments_text_only missing schema, easy_breadcrumb.settings:home_segment_validation_skip missing schema in Drupal\Core\Config\Development\ConfigSchemaChecker->onConfigSave() (line 94 of core/lib/Drupal/Core/Config/Development/ConfigSchemaChecker.php).
