RFR: 8202651: Test ActalisCA.java and ComodoCA fails

[Rajan Halade]

Please review this fix to update test certificates used in Actalis and 
Comodo CA interop tests. The bug also mentioned QuoVadisCA test but I am 
not able to reproduce the failure. For Actalis CA, I couldn't get 
revoked test certificate but the test is updated for valid certificate 
and will pass now by skipping expired revoked chain.
