Fix expansion of commands snippet

Browse Source 
The previous changed failed to account for command snippets which have
lists for bodies, not strings.
* yasnippet.el (yas-expand-snippet): Don't error if SNIPPET is a list
representing a command snippet body.
* yasnippet-tests.el (yas-expand-command-snippet): New test.
