Get rid of testtools so we can have sane reporting

testtools turns exceptions into _StringExceptions for unknown
reasons so let's get rid of that.

Then, in gabbi.report lets override exc_info_to_string so we just
don't do that. We want the actual exception information (which is a
tuple of type, exception, tb).

This gets us two things:

* one less dependency
* the ability for @FND to dig at the exception info as he likes,
  which is left as an exercise to him for a followup patch
