[SDKs] arv-put doesn't respect --replication for Keep blocks (unless you add --no-resume)

Description

Doing a simple arv-put that specifies --replication different than the default will ignore the replication for Keep blocks. They'll still be replicated to Keep at the default level. Here's a demonstration on the PGP tutorial data. The debug output shows it writing each block to two Keep services (each of two ports on keep0):

There is a fairly obvious bugfix at 8325a88. This code path happens when trying (but failing) to load state from the resume cache. I haven't actually managed to expose the bug with a test case, but I did add a related test: ensure the replication argument gets passed through to KeepClient (not just collections.create()).

The fix is good.

I've pushed a change that updates the test to tickle the bug, and (I hope) improve readability a bit. Your version was causing arv-put to fail setting up the cache at all (rather than loading it), which means it never got to the branch we wanted to test. My version mocks ResumeCache to make sure the load step specifically fails. It also saves us a bunch of filesystem manipulation.

I also changed x[len(x)-1] to just x[-1].

If those changes look good to you, I'd say let's merge this. Feel free to rebase and squash or whatever. Thanks.
