duplicate require causing error during upgrade

[ilyatregubov]

There are 2 appearances of require( 'importsnakes.php'); in upgrade.php, so if version was < 2018060404 upgrade will fail with the error

PHP Fatal error: Cannot redeclare game_importsnakes() (previously declared in /siteroot/mod/game/db/importsnakes.php:33) in /siteroot/mod/game/db/importsnakes.php on line 72
PHP Stack trace:
PHP 1. {main}() /siteroot/admin/cli/upgrade.php:0
PHP 2. upgrade_noncore() /siteroot/admin/cli/upgrade.php:182
PHP 3. upgrade_plugins() /siteroot/lib/upgradelib.php:1857
PHP 4. upgrade_plugins_modules() /siteroot/lib/upgradelib.php:512
PHP 5. xmldb_game_upgrade() /siteroot/lib/upgradelib.php:806

But it will pass on second run since it reached savepoint after first appearance
