Better replacement algorithm for blob urls in stack traces.

[jespertheend]

I just ran into an issue where a module tried to do

new URL("./some/path.js", import.meta.url);

Since import.meta.url was an object url, it threw an error:

TypeError: Invalid URL: '../some/path.js' with base 'file:///Users/Jesper/path/to/other/file.js'
const theUrl = new URL("../some/path.js", import.meta.url);
               ^
    at getSerialization (ext:deno_url/00_url.js:89:11)
    at new URL (ext:deno_url/00_url.js:380:27)
    at blob:null/7af13edf-0cac-4103-b56a-5129210edc73:100:16

This got me confused for a good while because the 'with base' reported a valid base.
Also it seems like the object url in the stack trace wasn't replaced for some reason.
