fix(dynamodb-helper): Incorrect attributes used in CheckDynamoDBProps

[biffgaut]

In the code below, the check should be against propsObject.dynamoTableProps.pointInTimeRecovery and propsObject.dynamoTableProps.pointInTimeRecoverySpecification

Thanks to @vicentenoriega for finding this.

  if (propsObject.pointInTimeRecovery && propsObject.pointInTimeRecoverySpecification) {
    errorMessages += 'Error - Either provide pointInTimeRecovery or pointInTimeRecoverySpecification, but not both.\n';
    errorFound = true;
  }
