[e2e] Add test which validates only 1 request is sent to the Security Provider API

[seaona]

Context: there has been an issue, where we sent additional requests to the Security Provider #18560 . This issue has been partially fixed by this PR #18598 and one more PR is pending in order to fix it completely.

What: add assertion in the security provider test, which validates that only 1 request is sent to the Security Provider API.

We'll be deprecating OpenSea's security provider once Blockaid's integration is ready. Should we de-prioritize this? cc: @seaona

yes, there is already a PR for the test, but the test won't pass because there was a pending task to solve on Security Provider code - since I think this won't be fixed as new prio is Blockaid, I guess this ticket and PR could be closed completely @bschorchit
