A function that wraps the getProperty function, which client
code can use if it is needed to identify when the json value of
a property is an IRI -- Internationalized Resource Identifier
If the value of the json value is a bare string, then it will be
wrapped in a json object with the string in the property 'id',
additionally that property will have a property 'isIRI' which will
be true for the literal string case, otherwise false meaning the
returned getProperty should be parsed as before.
