Test revoke token approval after swaps

[sprtd]

Add validation logic in test that guarantees that no token allowance exists if approval is revoked after a successful swap txn (fibrous and avnu)

Can I start working on this?

hey @sprtd
I'm going to test that when users revoke their token approvals after making swaps on Fibrous or Avnu (which are DEXs)
i will first:

Set up a test swap
Do the swap successfully
Revoke the approval
Check that the approval is truly zero/canceled
i will also check the before and after state of the swap

ETA is 1 day.
