cy.request failures are not obvious

When cy.request fails we get a stack trace that looks like this:

2) Todo MVC "before each" hook:
     CypressError: Error: connect ECONNREFUSED 127.0.0.1:9002

We should at explain that it was caused by the cy.request and additionally print out request data and/or response data as a nicely formatted (truncated) object.

This will help users debug cy.request failures.
