GEODE-3314: Fix DLockService token leak. And add a test so that we don't do that again. We had been unlocking the DLock on the remote server before freeing the local `DLockToken`. This meant that the local token got reused by another thread acquiring the same lock and the count went up and up and up (due to some logic that wouldn't decrease the count if it no longer owned the token). Tokens should no longer have usageCounts that climb over time, which means they should be released normally by freeResources.
