Host is stripped from protocol-relative urls

[44px]

How to reproduce:

1. Have app on http://my-app.dev
2. Make request to protocol-relative url //api.dev/posts/1

Expected behavior
Polly proxies this request to api.dev and writes response.

Actual behavior
Polly strips host from //api.dev/posts/1 making it into /posts/1 and then trying to send request to http://my-app.dev/posts/1 instead of original url.

I found two places in code where url is modified. Here is one which caused desribed behavior:

pollyjs/packages/@pollyjs/core/src/-private/request.js

Lines 53 to 60 in 73026d4

	/*
	If the url is relative, setup the parsed url to reflect just that
	by removing the host. By default URL sets the host via window.location if
	it does not exist.
	*/
	if (!isAbsoluteUrl(value)) {
	removeHostFromUrl(url);
	}

Seems like is-absolute-url check here can be swapped with custom implementation supporting protocol-relative urls
