TS-4507: Fixes to ensure SSN_CLOSE called after TXN_CLOSE.
Adding logic to ensure that SSN_CLOSE doesn't get called before TXN_CLOSE.
This involved deferring the session destroy further. Had to add some recursion
checks in HTTP2 to make sure we don't destroy the ssn object on the stack.

>
> One of our plugins will occasionally crash. It appears there is still a path
> for HTTP2 that has the SSN_CLOSE hook close before the TXN_CLOSE hook.
> Working through solutions that delay the SSN_CLOSE hook until after all the
> TXN_CLOSE hooks, but does not lose the SSN_CLOSE.
