Fixes test pipeline issue tpp

Since when we introduced the workToDoTimeout attribute to be set for TPP request in VCert, we have had some sporadic issues in tests with the following error:

[2024-11-21T09:44:32.149Z]     connector_test.go:2304: Unexpected status code on TPP Certificate Request.
[2024-11-21T09:44:32.149Z]          Status:

    "CertificateDN": "\\VED\\Policy\\<redacted>\\redacted.example.com",
    "Devices": [
        {
            "Applications": [
                {
                    "DN": "\\VED\\Policy\\<redacted>\\instance\\workload-17redacted55"
                }
            ],
            "DN": "\\VED\\Policy\\redacted\\instance"
        }
    ],
    "Error": "Certificate processing took longer than WorkToDoTimeout. Call certificates\/retrieve to get the certificate data",
    "Guid": "{c2XXXXXX-c7XX-4cXX-XXXX-1XXXXXXXXXX7}"
}

These tests had a very short timeout of 10 seconds set, which, in case TPP took longer that, our pipeline would fail.

This PR address that issue as well as some minor fixes
