Retry RDE report on SocketTimeoutException

It's likely that either 1) we should be doing this for more than a
SocketTimeoutException - we probably want to do this in the case of a number
of different transient failures 2) we don't want to do this at all because it
happens in a background task that will get re-run anyway.

In any case, this seems like the right fix and it addresses a problem we see
occassionally.
