Correct some issues with AttributionSource.Builder
1. The constructor that takes an AttributionSource doesn't copy all
fields.
2. The existence of mBuilderFieldsSet clears all fields copied from the
previously mentioned constructor leading to an almost blank
AttributionSource besides UID and fields that have been overridden
with setField() methods. It is not clear why these field flags were
introduced anyways.
3. build() always overwrites the token field to sDefaultToken, in the
copy case we want to preserve the token.
