rust: fix macaroon expiry check
There were two bugs with this code: the expiry timestamps were getting enclosed in double-quotes (which caused parse bugs), and the actual caveat check itself was backwards (expires < now instead of expires > now). An underlying issue was that these caveats weren't actually getting checked in the tests. Should fix a bug where users don't get auth'd correctly when logging in via mechanisms other than tokens.
