Reset a view shard if the signature is wrong
We encountered a case_clause error when reading the header for a .view
file as the response was {ok, {Sig, nil}} where Sig is neither the
expected sig or the pre-upgrade sig (though surely the pre-1.2 goop is
not firing anymore).
We now log this specific issue and then proceed as if we found no
valid header.
