Pass url into curlinfo hook for effective url

[whikloj]

Context

Issue #363

When checking for errors in a curl_multi I pull the effective url to log with the error.

$url = curl_getinfo($curl_handles[$x], CURLINFO_EFFECTIVE_URL);

Which currently fails with php-vcr

BadMethodCallException: Not implemented: CURLINFO_EFFECTIVE_URL (1048577)

IMHO it really should just return the request url parameter from the source YAML.

What has been done

• Added a nullable string parameter to the getCurlOptionFromResponse to pass in the URL (or null)
• Get the url from the self::$requests array of VCR\Request objects

How to test

• Before if you did a command like above you get the above error.
• Now you should get the url provided in the request -> url parameter

Todo

• [ ]
• [ ]

Notes

• I'm very new to php-vcr, so this might go against the pattern you are trying to work to. If so any guidance would be appreciated.

I'm using the 1.5 version to support some older versions of PHP. If this PR seems acceptable, would you be open to another patch release of that version?
