QPIDJMS-602: fix potential for session shutdown NPE during competing local and
remote closures
Make the ProviderFuture creation safe from NPE, validate a future is returned
and noop the
completion wait if not since the provider ref is gone already.
Add additional try-finally to ensure executor shutdown occurs.
(cherry picked from commit 82557f96f8da8767277db18f0aa7db7d5556a132)
> racing local and remote closures can NPE in session shutdown, cause executor

> Project: Qpid JMS
> Issue Type: Bug

>
> Following QPIDJMS-600, when local resource teardown (e.g due to a
> connection.close()) overlaps with similar teardown provoked by remote
> connection closure, the session shutdown attempts to await async send
> completions can NPE, causing it not to shut down the related completions
> executor, if it tries to use the underlying provider after it has gone.
