[FLINK-6320] fix unit test failing sometimes when deleting a temp dir
use a JUnit rule with a `TemporaryFolder` instead which should fix this
(alternatively, catching the exception may have fixed this symptom but using a
temporary folder should be even more save in case a real concurrency issue was
present)
