make_value_from_datastore errors for null values

[GoogleCodeExporter]

What steps will reproduce the problem?
1. my_model.credentials_property = None
2. my_model.put()
3. next time you load my_model error thrown

appreciate this is not very likely to happen, but it happened to me.

the error was with the logging lines - 188 + 189:
 - logging.info("make: Got a " + value)
 - logging.info("make: Got type " + str(type(value)))
throws:
TypeError: cannot concatenate 'str' and 'NoneType' objects
if value is None

changing to ...

if value:
  logging.info("make: Got a %s" % value)
  logging.info("make: Got type %s" % str(type(value)))

would fix the issue.
