fix #7

fixed #7.

By this way node will throw a meaningful error like this:

[[[[[ ~/git/meteor/mysql-test ]]]]]

=> Started proxy.
=> Started MySQL.
[MySQL] Performing initialization queries...
=> Errors prevented startup:

   While building the application:
   packages/mysqlServer/plugin/mysqlServer.js:171:1: ER_PARSE_ERROR: You have an error in your SQL syntax; check the
   manual that corresponds to your MySQL server version for the right syntax to use near 'REATE DATABASE chicks;
   USE chicks;

   CREATE TABLE `sexies` (
   `name` varchar(45)' at line 1 (compiling app.mysql.json)
   at Query.<anonymous> (packages/mysqlServer/plugin/mysqlServer.js:171:1)
   at runWithEnvironment (/tools/utils/fiber-helpers.js:112:21)

I don't know much about the meteor internal so I might miss something, but at least the error message can be shown normally now.
