Minor Description
Improve exception message when attempt is made to redeclare an exchange with a different type on a 0-10 connection.
Curently when attempting to do so the exception is fairly vauge, saying "Cannot redeclare with a different exchange type", whereas the equivalent message for 0-9-1 connections is something more helpful like: "Attempt to redeclare exchange: amq.topic of type topic to fanout". The 0-10 message should be brought in line with the 0-9-1 message for clarity and consistency.
