Fix regression: url not being added to response objects

v5.13.1

5.13.1

Add includeContentLength option

Adds this option so that responses calculate and add Content-Length header

Support combining function matchers with other options

So that e.g. .get(url => /\?/.test(url)) will work

Avoid uncaught error in promise

In future versions of node this is likely to be thrown as an error, so getting ahead of the game with this commit

redirected

Supports using a __redirectUrl property in order to mock a fetch that has followed redirects

v5.11.2

Fixes bug where flush() was resolving too quickly

v5.11.1

Fixes bug caused by including node-fetch's Headers implementation in browser code
