[SPARK-11869] [ML] Clean up TempDirectory properly in ML tests
Need to remove parent directory (```className```) rather than just tempDir
(```className/random_name```)
I tested this with IDFSuite, which has 2 read/write tests, and it fixes the
problem.
CC: @mengxr Can you confirm this is fine? I believe it is since the same
```random_name``` is used for all tests in a suite; we basically have an extra
unneeded level of nesting.
