Fix crash for handshake failure in ssl infra

Issue:
------
on handshake failure, session triggers sever notify_close
handler as well, while having only one session for which
handshake failed no issue was observed, however if there
are existing established/closed sessions present in the
ref map it results in assertion.
Since it is expected that session will be added to ref_map
only when the handshake is complete

Fix:
----
since SSL handshake is done in Server context, close
session should be called without server notify flag.

Added test-case for the same
