`purgeRequestQueue` doesn't purge the default `RequestQueue`

[barjin]

The following snippet will only log AAAAA, as the second crawler won't run (the default RQ contains the handled first request only after the execution):

import { CheerioCrawler } from '@crawlee/cheerio';

const crawlerA = new CheerioCrawler({
    requestHandler: () => console.log("AAAAA"),
});

await crawlerA.run(['https://crawlee.dev'])

const crawlerB = new CheerioCrawler({
    requestHandler: () => console.log("BBBBB"),
});

await crawlerB.run(['https://crawlee.dev'], { purgeRequestQueue: true });

INFO  CheerioCrawler: Starting the crawler.
AAAAA
INFO  CheerioCrawler: All requests from the queue have been processed, the crawler will shut down.
INFO  CheerioCrawler: Final request statistics: {"requestsFinished":1,"requestsFailed":0,"retryHistogram":[1],"requestAvgFailedDurationMillis":null,"requestAvgFinishedDurationMillis":728,"requestsFinishedPerMinute":71,"requestsFailedPerMinute":0,"requestTotalDurationMillis":728,"requestsTotal":1,"crawlerRuntimeMillis":844}
INFO  CheerioCrawler: Finished! Total 1 requests: 1 succeeded, 0 failed. {"terminal":true}


INFO  CheerioCrawler: Starting the crawler.

This behaviour is not documented very well and IMO is wrong given the param values.

tested only locally (with @crawlee/memory-storage).

Adding the following call actually clears the RQ and runs the request through both crawlers:

-import { CheerioCrawler } from '@crawlee/cheerio';
+import { CheerioCrawler, RequestQueue } from '@crawlee/cheerio';

const crawlerA = new CheerioCrawler({
    requestHandler: () => console.log("AAAAA"),
});

await crawlerA.run(['https://crawlee.dev'])

const crawlerB = new CheerioCrawler({
    requestHandler: () => console.log("BBBBB"),
});

+const queue = await RequestQueue.open();
+await queue.drop();

await crawlerB.run(['https://crawlee.dev'], { purgeRequestQueue: true });

The bottom line is that each crawler instance should have its own set of storages.
