Ensure FileTest.dart deletes temporary directories

Ensure FileTest.dart deletes temporary directories

The FileTest.dart did not delete the created temporary directories. This
was caused by the sub-test testOutputStreamWriteAppend not working.

The close handler for a file FileOutputStream is newer called.

how do we know that the output has been written to outStream when we write to
appendingOutput?

Output streams are buffering streams which will flush buffered data when
closing.
