Grunt validate running slow and timing out on Sata drives

If you are building stuff for Ghost on an older or slow Sata hard drive the test begin loads a new database each time which is very slow and timeouts at 15 seconds giving errors like this:

``` bash
Ghost Error:  { [Error: SQLITE_ERROR: no such table: settings] errno: 1, code: 'SQLITE_ERROR' }
Error: SQLITE_ERROR: no such table: settings
    at Error (native)
```
