[API Client]sketch.attribute_table value error

[jaegeral]

Describe the bug When pulling sketch.attribute_table() via API it is causing a value error if only intelligence attribute is there.

To Reproduce

1. Create a blank Sketch
2. Add a piece of intel to it
3. run api client sketch.attribute_table

sketch.attributes:

Attributes: {'intelligence': {'ontology': 'intelligence', 'value': {'data': [{'externalURI': 'google.com', 'ioc': '1.2.3.4', 'tags': ['foo'], 'type': 'ipv4'}, {'externalURI': 'fobar.com', 'ioc': '3.3.3.3', 'tags': ['aaaa'], 'type': 'ipv4'}]}}}

Error:

Based on the content of sketch.attributes, the current way of implementation likely never worked / was used, as in the top level of the sketch.attributes, those columns do not exist.

Representing this type of data in a single pandas dataframe is not really useful, so I will add a comment to the method that it will be deprecated at some point (in case some one is actually using the method, which I doubt given above error I assume this has never worked).
