Once more, GenericJson.clone() method blows up when trying to clone Google reads

This is related to #293, but #293's fix doesn't work for this problem.

From the Hellbender project (broadinstitute/hellbender#650):

When we copy a Google read (ie., a com.google.api.services.genomics.model.Read), we currently call into the GenericJson.clone() method, which uses reflection to deep copy the fields. However it seems to run into difficulty with `com.google.common.collect.Lists$TransformingRandomAccessList`.

Here's the stack trace:

```
