Include description columns in data requests

[alrocar]

Description columns are removed from the request because the copyto query was failing.

The problem may be due to copyto does not support POST requests.

To test this:

• Remove the FIXME in cc.data method
• Run the test_data test

Why is this related with POST? Query length?

[alrocar]

Yes I was assuming it was because the query length. We were including the whole columns descriptions in the DO query, but as per this comment it may be not necessary.

SO I guess we can remove the FIXME and close this issue.

Eventually the POST issue may be a problem, but I guess this is not something we have to fix in CARTOframes.
