Incorrect parameter to QUnit.log

In function push:

``` javascript
var details = {
result: result,
message: message
};
// Snip

QUnit.log(details);
```

The parameter passed to Qunit.log is a callback, not some data.

Therefore if you do a normal Qunit equal:

``` javascript
equal("value1", "value1", "Some information");
```

this will throw an error while QUnit runs through its logging callbacks.
