 There is a bug in how the decoder type is set for the syndrome decoder.
 Consider

 {{{
 sage: C = codes.HammingCode(GF(5), 3)
 sage: D = C.decoder("Syndrome")
 sage: C.minimum_distance()
 3
 sage: D.maximum_error_weight()
 1
 sage: D.decoder_type()
 {'complete', 'hard-decision', 'might-error', 'unique'}
 }}}

 The last line should not have had "might-error" but instead should have
 had "always-succeed" and "minimum-distance".
