Do not exit loop if answers are still expected or conflicts known.

This will allow sending requests even when no conflict occur. For example,
it can happen to avoid a deadlock on storage nodes (store again, no conflict
to resolve).
Also, call conflict resolution as soon as a conflict is known, to reduce
tpc_vote duration.
