[Rest] OAuth2 bearer tokens and refresh of tokens

[Fleny113]

Describe the bug:
Given a Bearer token got after a code exchange with discord the token gets used to do requests and discordeno creates queues mapped in the restManager.queues with the following key: Bearer <token here>/<url here>¹. The problem is when the access token gets refreshed (even if it's before it expires) the token changes but the ratelimit is still the same, also the old queue that was created might still have pending request to send but since refreshing a token implies invaliding the old one the pending requests will fail with a 401 & Unauthorized error and if a new request gets sent before the ratelimit for an endpoint is refreshed² it will fail with a 429 & Too many requests

To Reproduce:

import { createRestManager } from "@discordeno/rest";

const token = "<bot token>";
const secret = "<client secret for the OAuth2 exchange>";
const id = "<your bot id>"
const code = "<the code given by an oauth2 code exchange flow>"

const manager = createRestManager({
    token,
});

let token = await manager.exchangeToken(id, secret, {
    grantType: "authorization_code",
    redirectUri: "<redirect url of the application>",
    code,
});

await manager.getGuilds(token.accessToken);

token = await manager.exchangeToken(id, secret, {
    grantType: "refresh_token",
    refreshToken: token.refreshToken,
    accessToken: token.accessToken,
});

await manager.getGuilds(token.accessToken);

Expected behavior:
There shouldn't be an Invalid request performed for 429 & Too many requests

Screenshots:

The censored lines in the log are an input for the code to exchange

Footnotes

1. The / is in fact part of the url, it is explicit in to separate the token and url ↩

2. For example: a token is used to do a request on /users/@me/guilds and then the token refreshes and another request is sent to that same url it will fail ↩
