Servers should not send duplicate intermediate certificates.

Browse Source 
Motivation:
Servers sometimes send duplicate intermediate certificates.

Modifications:
OpenSslKeyMaterialManager.setKeyMaterial() dedups aliases before calling SSL.setCertificateChainBio().

Result:
Servers no longer send duplicate itermediate certificates.
