Merge "Force source to always be included in JSON"

Force source to always be included in JSON

Modified RequestInfo to pass source to JSON, even when it has the
default value.  Ordinarily, this is unnecessary when the default
value is null, but in this case, the default value is not null,
thus other code to which the JSON is passed expects it to be
populated.
