http_test not working

The error:

```
➜  logger git:(hotfix/issue4) % go test        
--- FAIL: TestShouldChangeAllNamespacesLevel (0.00s)
    http_test.go:23: Level should be [123 34 108 101 118 101 108 34 58 34 100 101 98 117 103 34 125] But got 4 4
FAIL
exit status 1
FAIL    github.com/NeowayLabs/logger    0.003s
```

Is there something wrong on my env ?
