Call to undefined method

With Laravel 5 and Jenssegers installed you get this error:

```
Call to undefined method Jenssegers\Agent\Facades\Agent::platform()
```

Request code:

```
$agent = new \Agent;
return $agent->platform();
```

If I call it statically it returns false.

```
return \Agent::browser($request->header('user-agent'));
```

Note: this is a clean install with the latest Lavarvel 5.2.x and jenssegers/agent (v2.3.3)

Start by reproducing the reported calls in a clean Laravel 5.2.x installation with jenssegers/agent v2.3.3. Trace how the Agent facade and instance resolve platform() and browser(), then verify that the documented usage no longer raises an undefined-method error and that the static call returns the expected result.
