Sometimes the netflix plugin marks an episode as not seen and deletes the playcount field. This makes watching the episode or film impossible as when creating the infos object this field is accessed. Here is an example exception.

Instead we use the dictionary get method so that we can fall back to 0 when the attribute is absent.

@liberty-developer is there anything that is blocking my request? The only complaint I saw is from travis-ci and it affects files that are not affected by my patch.
