Issue:
URLs Ending with Comma Cause "No match for HTTP request" Error
Per request here https://github.com/node-nock/nock/issues/81#issuecomment-342894207, creating a new issue for when URLs end with a comma ( e.g. http://example.com?s=goog, ) 

```javascript
const data = {ok: true};
const stocks = ['goog'];  // fails when only 'goog' is added. Add another item "gm" and it will pass.
const httpHeaders = {
  'Access-Control-Allow-Origin': '*'
};

nock('http://example.com')
  .get("/baz?s=" + stocks.join(','))  // please note how we join with a comma which works if length > 1
  .reply(200, {ok: true}, httpHeaders)

const request = http.request({
  hostname: 'example.com',
  port: 80,
  path: '/baz?s=goog,',  // please note how the path ends with a comma ",".
  method: 'GET',
  headers: {
    'Access-Control-Allow-Origin': '*'
  }
})

request.on('error', console.log)
request.write(JSON.stringify(data))
request.end()
```

This throws the following error:

> Error: Nock: No match for HTTP request.

Here is the runkit:  https://runkit.com/sam3k/5a048e1d8658b00011f9e174

To fix, just need to be sure it does not end with a comma:

```javascript
const data = {ok: true};
const stocks = ['goog','gm'];  pass.
const httpHeaders = {
  'Access-Control-Allow-Origin': '*'
};

nock('http://example.com')
  .get("/baz?s=" + stocks.join(','))  
  .reply(200, {ok: true}, httpHeaders)

const request = http.request({
  hostname: 'example.com',
  port: 80,
  path: '/baz?s=goog,gm', 
  method: 'GET',
  headers: {
    'Access-Control-Allow-Origin': '*'
  }
})

request.on('error', console.log)
request.write(JSON.stringify(data))
request.end()
```

Things to note:
* It will fail when `const stocks = ['goog']` and `path: '/baz?s=goog,',` (Ends with comma)
* but it will pass when `const stocks = ['goog', 'gm']` and `path: '/baz?s=goog,gm',` (Doesn't end with comma)

Pull request description:
fix: URLs Ending with Comma Cause "No match for HTTP request" Error (#1018)
Slight change to the error message thrown comparing the header received with the header expected. The idea is that hopefully, it will help identify more quickly what exactly went wrong. The new error message will look something like this:

`Nock: No match for request {"method":"GET","url":"http://google.com/?num=1str=fou"} Got instead {"method":"GET","url":"http://google.com/?num=1str=fou@#"}`

closes #1018
