In some cases the callback function equals undefined which doesn't equal null. Changing the === operator to == makes it check for both null as undefined.
This fixes the usage of migration.init(connection, __dirname + '/migrations'); where otherwise migration.init(connection, __dirname + '/migrations', function(){}); had to be used
