handling of the --idlist option should check that the values work with the migration

Problem/Motivation

If a migration has multiple source keys, but you don't give enough values in the --idlist option, then you get this crash:

 [error]  TypeError: Argument 1 passed to Drupal\migrate\Plugin\migrate\id_map\Sql::setUpdate() must be of the type array, bool given, called in /var/www/web/modules/contrib/migrate_tools/src/Commands/MigrateToolsCommands.php on line 883 in Drupal\migrate\Plugin\migrate\id_map\Sql->setUpdate() (line 844 of /var/www/web/core/modules/migrate/src/Plugin/migrate/id_map/Sql.php) #0 /var/www/web/modules/contrib/migrate_tools/src/Commands/MigrateToolsCommands.php(883): Drupal\migrate\Plugin\migrate\id_map\Sql->setUpdate(false)
#1 [internal function]: Drupal\migrate_tools\Commands\MigrateToolsCommands->executeMigration(Object(Drupal\migrate\Plugin\Migration), 'two_images_para...', Array)

This is because array_combine() returns FALSE if the two arrays aren't of equal length:

          $migration->getIdMap()->setUpdate(array_combine($keys, $source_id_values));
