Title: Log message on attempted parallel blockchain download; javadoc edit.

Changes I made on my repo while diagnosing a problem. The log message written during an attempted parallel download indicates it's the `blockChainDownloadLocked()` method writing the log message, but not which method invoked `blockChainDownloadLocked()`. I changed that.

Also I had difficulty understanding the javadoc description of `AbstractBlockChain.getOrphanRoot()`. I made some slight modification to that text and its formatting.
