Changed to the well known pattern using collect() für multi-events.

Fix NetworkInterfaceSuite.TestRemove random failure

The NetworkInterface type must be serialised as %#v not %v for errors.NotFoundf so the GoString method gets used. Also improve the test error match to ensure the correct serialisation is used. Without this change, the test could randomly fail if the bson id happened to contain an 0x0A byte, as `.*` does not match newlines.
