on foo_create, facebook returns an ID (string) that blows up map_data

[klochner]

example:

post = Mogli::Post.find(some_post_id)
post.comments_create({message: "hello"})

The call to client.post will return a string, which blows up with this stack trace (line numbers may be off):

 NoMethodError - undefined method `each' for  
                       "20151777981831111_57381111":String:

I'm hesitant to try hacking a fix, since there may be other non-hash/array values that need to be handled by other calls. This may be fixable by setting a default field as done here:

#127

@yitaosun - can you take a look? This looks similar to the fix you put in for location.

how annoying. I think it's sane to create an instance with that as an id if we get a non hash. We could just turn a string into {id: string}

I don't think Facebook should be allowed to do API design :)
