Marco Arnulfo 452ab51ab8 fix(sign): refuse to sign a field whose /V is not a signature (#1328 ) (#1402 )

Follow-up to #1374. Signing an existing field refused a field whose /V
is a signature dictionary and signed one whose /V is missing or null,
but a /V that is neither (an empty string, a number, a name, an array)
was treated as unsigned and overwritten with the new signature.

Signing such a field by name now fails with "the value of the field
... is not a signature" and leaves the document as it is. A missing or
null /V, direct or indirect, still signs, and a signed field is still
refused as already signed. The signature list is unchanged: it still
shows such a field as unsigned, since it carries no signature.

Adds a_field_whose_value_is_not_a_signature_is_refused_by_name, which
fails before this change.
