fe2 terminate doesn't work

[dzubo]

fe2 terminate inst1 returns error:

Traceback (most recent call last):
  File "/Users/zubo/anaconda/envs/fastai/bin/fe2", line 10, in <module>
    sys.exit(main())

    return cls(e, d[0])
IndexError: list index out of range

Steps to reproduce:

1. Create a base ami, as described here: https://www.fast.ai/2019/02/15/fastec2/
2. fe2 launch inst1 base 80 m5.large
3. Wait for the instance to launch.
4. fe2 terminate inst1

Also, it works fine for the spot instances, fe2 terminate spot1.

Perhaps try this form fe2 get_instance inst1 terminate
