Remove the race condition between new process creation and context release (#12342)

Browse source 
* Remove the race condition between new process creation and old process releasing remote context

Previously there was a race condition where the getId() method would return the new context ID even
though the release was for the old context.  This changes it to send the "initial" context ID with
the release message to ensure there is no race.

* fetch context ID from remote in sandbox mode
