fix: don't override DraftReply.send_status based on application-level…

… state

Since #750, application-level state transitions (logging in, logging
out, and switching into offline mode) call
securedrop_client.storage.mark_all_pending_draft_replies().  However,
one or more SendReplyJobs (and their underlying POST requests to
"/sources/<source_uuid/replies") may be in flight on the network at that
time, whether or not the application is connected (or even running) to
receive their responses.  Until we have better (ideally generalized)
logic around upload jobs that have not yet been confirmed by the server,
these application-level events should not make assumptions about the
results of jobs that have already been dispatched.
