TransferManager.exists() methods should maintain (and use) the NotFoundCache.

[jdcasey]

We need a test that verifies that the NFC isn't affected by current TransferManager.exists() method implementations, then we need to fix them so they do use it. If the NFC contains a missing-path entry for something we're about to check existence for, we should short-circuit and return false. If we do check existence, and it comes up false, we should add it to the NotFoundCache.

@ruhan1 I assigned this to you since you are probably more familiar with that section of code than anyone else. If you don't have time for it, assign it to me and I'll make sure it's on our radar in the new year. Thanks!

No problem. I have plenty of time in the year 2017.
