argparse uses repr on the choices when throwing an error, which causes our u-prefixed string literals to print out with the prefix when running the code42cli on python2: (#14)

```
# code42 securitydata notvalid
usage: code42 securitydata [-h] {send-to,write-to,print,clear-checkpoint} ...
code42 securitydata: error: invalid choice: 'notvalid' (choose from 'send-to', u'write-to', u'print', 'clear-checkpoint')
```

So I'm removing those from the relevant strings.
