active debug session is not properly updated

[akosyakov]

Toggle skipping this file command from node-debug extension does not work because of it https://code.visualstudio.com/docs/nodejs/nodejs-debugging#_skipping-uninteresting-code-node-chrome

Also custom request is sent with bogus arguments with command id as a session id:
