ARTEMIS-1276 delete MessageEvictionTest (feature not implemented)
The test is broken. It can be fixed by doing
```java
FakeTransportConnector(URI uri) {
setServer(new TransportServer {
@Override
public URI getConnectURI() {
return uri;
}
but then the test would fail because message
eviction is not supported by Artemis.
