[BUG] Proxyman is unable to intercept HTTPS after re-installing new Proxyman Certificate

[NghiaTranUIT]

🐶 Brief

Proxyman is unable to intercept HTTPS after re-installing new Proxyman Certificate.

Reproduce steps

1. Install Certificate and Intercept any https request successfully
2. Don't close app, then opening the Keychain and delete Proxyman CA certificate
3. Back to Proxyman, the app present the error status -> Correct behavior at Content layout settings are not persisted #334
4. Install new certificate
5. Reload the https request
6. Still get error 💥 until restarting the app and try again -> work

Problem

It reveals that CertificateService is still remaining the CertificateIdentity list in memory and disk, so the next time we try intercepting the https request with new Proxyman CA Certificate, it won't work since the chain certificate doesn't match.

👑 Criteria

• Able to intercept immediately after re-installing the certificate without restarting the app
• Delete all Leaf certificates in memory and disk after installing new certificate.
