If you have `ec2_instance_type` set in your `mrjob.conf`, the `--ec2-slave-instance-type` option does nothing.

This is actually a pretty severe bug. It ended up this way because of the way we do defaulting in `mrjob`.

For now, either of these workarounds will work:
* Replace `ec2_instance_type` in your `mrjob.conf` with `ec2_master_instance_type` and `ec2_slave_instance_type` entries.
* Use `--ec2-instance-type` on the command line in place of `--ec2-slave-instance-type`.
