Fix type of update_fields parameter to Model.save (#437)

Browse Source 
Sending in a single string leads to unexpected behavior and the method
accepts any iterable, not just sequences, of strings.

Technically sending in a single string is still allowed because a string
is an iterable of strings, but this way the intention of that argument
is clearer.
