Logger prints an absolute URL for a relative request URL

[kettanaito]

Describe the bug

When performed a request relative to the current origin, the logger outputs an absolute URL in the browser's console.

Environment

• msw: 0.16.0

Chrome Version 81.0.4044.138 (Official Build) (64-bit)

To Reproduce

Steps to reproduce the behavior:

1. Setup an interception for POST /login
2. Perform the POST /login request.
3. See the absolute URL in the browser's log.

Expected behavior

Requests performed relatively to the current origin are displayed without the origin in the browser logs:

[MSW] 00:00:00 POST /login (200)

Screenshots

If applicable, add screenshots to help explain your problem.

The req.referrer contains a trailing slash (/), while req.url.origin does not. The logic that determines whether a request URL is relative should swap places those two:

const isLocal = req.referrer.startsWith(req.url.origin)
