Fix body.exec is not a function

[halkeye]

Re-add support for matching body to query string regex

Fixes #1005 and #1004

This was working before the recent change to body parser.

From the docs:

The request body can be a string, a RegExp, a JSON object or a function.
var scope = nock('http://myapp.iriscouch.com')
                .post('/users', /email=.?@gmail.com/gi)
                .reply(201, {
                  ok: true,
                  id: '123ABC',
                  rev: '946B7D1C'
                });
