assistant: Get back in sync with XMPP remotes after network reconnection, and on startup.
Make manualPull send push requests over XMPP. When reconnecting with remotes, those that are XMPP remotes cannot immediately be pulled from and scanned, so instead maintain a set of (probably) desynced remotes, and put XMPP remotes on it. (This set could be used in other ways later, if we can detect we're out of sync with other types of remotes.) The merger handles detecting when a XMPP push is received from a desynced remote, and triggers a scan then, if they have in fact diverged. This has one known bug: A single XMPP remote can have multiple clients behind it. When this happens, only the UUID of one client is recorded as the UUID of the XMPP remote. Pushes from the other XMPP clients will not trigger a scan. If the client whose UUID is expected responds to the push request, it'll work, but when that client is offline, we're SOL.
