Add connection id for on-demand mode.

Long-lived zones could send their end events without begin events in a
following scenario:

1. On-demand connection is made.
2. Zone begin is emitted, m_active is set to true.
3. Connection is terminated.
4. A new connection is made.
5. Zone end is emitted, because m_active is true.

To this point it was assumed that all zone end events will happen before
a new connection is made, but it's not necessarily true.
