[roll] Roll fuchsia [fxfs] Use normal volume termination for tests
ExecutionScope now completes all in-flight requests upon termination, so
we no longer need to explicitly wait for tasks to complete. This brings
the TestFixture closer in line with actual fxfs shutdown, which when
terminating volumes, calls shutdown() followed by wait() on the
ExecutionScope.
Update and simplify some tests which were implicitly relying on this
behaviour.
Test: fx test fxfs-platform-test
