fix column_family_test asan

Summary:
stop calling Close() at the end of tests holding a compaction pressure token since it causes the write controller to be deleted while it's still needed. these calls were pointless anyways since Close() is already called in the test's destructor.
Closes https://github.com/facebook/rocksdb/pull/2367
