unhandledRejection reason lack of stack

[imchao9]

when I run the migration, I get [ERROR] undefined, and the shell exited,
then I check the code , and found that, in api.js

function registerEvents() {

  process.on('uncaughtException', function(err) {
    log.error(err.stack || err);
    process.exit(1);
  });

  process.on('unhandledRejection', function(reason) {
    log.error(reason.stack);
    process.exit(1);
  });
}

then I print the reason, and found that:

migratetiger_1  | [ERROR] undefined
migratetiger_1  | { err: null,
migratetiger_1  |   originalErr:
migratetiger_1  |    { Error: ER_BAD_FIELD_ERROR: Unknown column 'run_on' in 'order clause'

migratetiger_1  |      index: 0,
migratetiger_1  |      sql: 'SELECT * FROM `migrations` ORDER BY run_on DESC, name DESC' } }

so the reason don't have slack, can we log the reason?

@junchaozhang Edge case yeah, I guess this happened on the unhandledRejection event? Then we probably should do the the same as for uncaughtException.
