Raise save errors

[liamhuber]

The pickle storage back end wasn't actually raising unavoidable errors in the save process! So it would just silently fail. Here, we catch and raise any error that remains when we've exhausted our attacks (in this case, pickle and cloudpickle).

Identified in #614. If the data there is indeed un-cloudpickle-able, then this also closes that issue.
