call cricket::BasicPortAllocator::Initialize() here to initialize the parent

nit: Do you really need this condition? AFAICT network_manager_ should always be
set. If the constructor can take nullptr for network_manager_, can you please
add comments about this in the header?

Done.

I didn't see any "RTC_DCHECK(network_manager_)" so I assumed it was possible for
it to be null. I'll add that DCHECK.
