Fix connstr trust_store_path override if trustStorePath is not provided in ConnectOptions SecurityConfig

Currently the SDK automatically overrides the connstr trust_certificate param with the SecurityConfig trustStorePath even if the trustStorePath is undefined.

The SDK should only override the connstring if the trustStorePath from the ConnectionOption's SecurityConfig was populated. Also, the SDK should be able to correctly treat a `trust_store_path` connstring param as the `trust_certificate` to pass into the C++ SDK.
