There's a fix in 2885478: Install error .
Basically the Namespace for cardinality and result moved.

OLD

cardinality = \Drupal\webform\WebformHandlerInterface::CARDINALITY_UNLIMITED,
results = \Drupal\webform\WebformHandlerInterface::RESULTS_PROCESSED,

NEW

cardinality = \Drupal\webform\Plugin\WebformHandlerInterface::CARDINALITY_UNLIMITED,
results = \Drupal\webform\Plugin\WebformHandlerInterface::RESULTS_PROCESSED,
