Break the text in the error field of cider-test-error-report

Here is an example of how the error of a failing test:

The problem I'm having is that this is quite unreadable, as it's just one long line and I have to scroll to read it all.

If I hit RET on the error to get the stracktrace buffer to popup, I can read the message with proper text breaks. This is now my current workflow.

It looks this is just dumping the ExceptionInfo on one line. Perhaps we can split it into msg and cause and wrap the message text so it's readable without scrolling?

Formatting the exception cause message does make sense to me. I've ran into that problem as well.

Yeah, there's definitely room for improvement here. I wonder why the line wasn't wrapped though, as I seem to recall such long messages were wrapped for me.

@jeffvalk Any thoughts on this?

I seem to recall that wrapping the error text broke some other formatting, so I kept it simple. That made sense then, but I certainly agree it would be better wrapped.
