Fix a state transition bug (chain manager infinite loop, oops)

    %% We have a small problem for state transition sanity checking in the
    %% case where we are flapping *and* a repair has finished.  One of the
    %% sanity checks in simple_chain_state_transition_is_sane(() is that
    %% the author of P2 in this case must be the tail of P1's UPI: i.e.,
    %% it's the tail's responsibility to perform repair, therefore the tail
    %% must damn well be the author of any transition that says a repair
    %% finished successfully.
    %%
    %% The problem is that author_server of the inner projection does not
    %% reflect the actual author!  See the comment with the text
    %% "The inner projection will have a fake author" in
    %react_to_env_A30().
    %%
    %% So, there's a special return value that tells us to try to check for
    %% the correct authorship here.
