Set TLS cert options before calling connect on client, so verify works (#3774)

Browse Source 
When connecting using transportTraits, the CA and client certificates are ignored after the initial _client->connect() is called. This is because on connect, WiFiClientSecure will call start_ssl_client with _CA_Cert and other cert options set to null unless setCACert, setCertificate etc. are called before connect. Running _transportTraits->verify after connect therefore does exactly nothing. It's easy to verify that this is the case by passing a CACert to HTTPClient with verbose logging enabled - the logs will say "WARNING: Use certificates for a more secure communication!" which is only present when both PSK and CA are null. This change fixes the issue.
