fix(Search): Change mapping of flattened dataset

When flattening the dataset for indexing map a field's displayName
to its value using the path array rather than using the displayName.
This handles cases where the displayName is being used to actually
change the name to something semantically meaningfulrather than as
a way to alias dot notation.
Fixes IQTLabs#300.
