  1. server: Return nullopt when process_context is nullptr 

    The InstanceImpl::processContext() function returns a ProcessContextOptRef
a.k.a. absl::optional<std::reference_wrapper<ProcessContext>>.  When
InstanceImpl::process_context_ is nullptr, the returned value an
absl::optional with a value of std::reference_wrapper<>(nullptr),
better known as an illegal reference to nullptr.  While everything is
fine in the InstanceImpl, anyone who tries to use the returned
reference will be greeted with a crash.

This commit follows the lead of the initializer of InstanceImpl::api_
and returns absl::nullopt when InstanceImpl::process_context_ is
nullptr.

Risk: Low
