OboeTester crash when running disconnect test

[flamme]

This is from internal report by Xiaotong at b/330947899. From the log, I believed it was caused by the error callback arrived after the stream was closed. When the stream was opened with the shared pointer, the shared pointer of the oboe stream was released when the stream was closed. However, when the error callback arrived, oboe would find the shared pointer was null and then call the error callback via the raw pointer. That finally resulted in a crash.
