Switching from offline back to online

Nobody has claimed this yet.

Hi there!

I have this two methods in my test-class:

```
public class ContentLoaderTest {

@Test
public void loadContent() throws Exception {

// just for sure enable both internet connection types
TestButler.setGsmState(true);
TestButler.setWifiState(true);

// place Thread.sleep(5000) here and everything is fine ;)

// networking here is failing

}

@Test
public void loadContentOffline() throws Exception {

TestButler.setGsmState(false);
TestButler.setWifiState(false);

try {

// networking here seems to be offline

} finally {
// enable it again
TestButler.setGsmState(true);
TestButler.setWifiState(true);
}

}

}
```

Method `loadContentOffline()` is started first and even if internet connectivity is reenabled again the second method is offline. It works with Thread.sleep().

Start with the ContentLoaderTest methods and the TestButler.setGsmState(true) and setWifiState(true) calls described in the report. Reproduce the test order and check whether connectivity state is restored asynchronously; done means loadContent succeeds after loadContentOffline without Thread.sleep().
