Handle SQL error code 'HY000' in realtime

[stnguyen90]

What does this PR do?

SQL can throw an error where the code is a string like 'HY000':

appwrite-realtime | [Error] Type: PDOException
appwrite-realtime | [Error] Message: SQLSTATE[HY000]: General error: 2014 Cannot execute queries while other unbuffered queries are active.  Consider using PDOStatement::fetchAll().  Alternatively, if your code is only ever going to run against mysql, you may enable query buffering by setting the PDO::MYSQL_ATTR_USE_BUFFERED_QUERY attribute.

but $server->close() expects an integer. This change ensures we only pass an integer into $server->close().
