Cannot abort delayed retries

[veloware]

Describe the bug
When using retries, when the fetch is in the delay stage, i.e. delayed between retries, calling the abort function from the useFetch() hook has no effect.

⚠️ Make a Codesandbox ⚠️
Please do this to easily reproduce the bug.

To Reproduce
Steps to reproduce the behavior:

• attach the abort() function to a button
• make a fetch call that will cause a retry, with a reasonable delay for testing, say 5 secs.
• after the first request has fullfilled and the fetch hook will delay for 5 secs before making the next request
• during the delay, before the next request happens, click the button to call abort()
• nothing happens, and the next request will eventually happen after the defined 5 secs.
• click the button whilst the request is still in flight
• it is finally aborted

Expected behavior
If delays are possible, it shouldn't matter when the abort is clicked, the subsequent requests should be aborted, not just an in flight request.
