TemporaryBufferTest: Suppress "should be managed by try-with-resource"

In most of the tests, the temporary buffer is explicitly destroyed in
a finally block after being closed. This is not possible if using the
try-with-resource construct, because the variable is not accessible in
the finally block scope.
