Checkout error.

[Sormany Silva Dantas]

After the update to version 0.6.0an, the command checkout present problems.

$ tst checkout2 sd_acrescimo
Traceback (most recent call last):
  File "/home/sy/.tst/commands/tst-checkout2", line 120, in <module>
    main(text_in_file)
  File "/home/sy/.tst/commands/tst-checkout2", line 98, in main
    save(response_json, text_in_file, is_checkout=True)
  File "/home/sy/.tst/bin/tstlib.py", line 628, in save_activity
    save_yaml(data['name'] + '.yaml', tstyaml)
  File "/home/sy/.tst/bin/tstlib.py", line 584, in save_yaml
    if '\n' in field_value:
TypeError: argument of type 'NoneType' is not iterable

The directory of the activity is created but contains only the yaml file. This activity also has the reference solution, but it is not downloaded.

$ ls
sd_acrescimo.yaml
$ tst status
This is not a tst directory.

This is happening only with this activity. Why?

@daltonserey, I believe that the problem is only with the activity. In the other activities, the command is working normally.

This error indicates that one of the mandatory fields of your activity is null (or undefined). For now, I'm gonna update checkout so it saves the activity with the field as null. However, this requires I patch the commit script. It shouldn't allow a null value for any of the activity properties.

Just released 0.6.0ap. Now, whenever an activity is read from the local directory, it is validated. If the activity does not validate the operation is aborted with an appropriate message.
