MySqlTransaction.Dispose throws exception

[bgrainger]

The following code throws a SocketException that obscures the real exception (MySqlException: Got a packet bigger than 'max_allowed_packet' bytes):

using var connection = new MySqlConnection(ConnectionString);
connection.Open();
using var transaction = connection.BeginTransaction();
connection.Execute("insert into bigblobs(`data`) values(@data);", new { data = new byte[LARGE_NUMBER] }, transaction);

The exception that's thrown is:

Unhandled exception. System.Net.Sockets.SocketException (10053): An established connection was aborted by the software in your host machine.

MySqlTransaction.Dispose should not throw an exception, as it obscures the real exception that's causing the call stack to be unwound.

Fixed in 1.3.0.
