Add missing client cert (#729)

* Updated GitVersioning package to fix issue with loading native libgit lib. Added check for missing HttpClientHandler

* fixed type

* HttpClientHandler is null when trying to get client certificates for web socket connection. Added direct configuration of client cert instead of via HttpClientHandler

* fixed indentation warning

* re-added certs from httpclienthandler if present
