changed test for empty json in getContentAsDataFrame()

[geneorama]

oops, forgot that we use "issue" instead of "iss" for the branch names.

Anyway, pretty straightforward fix. I think the problem might have been introduced by Socrata, or might have been introduced by a change in httr, or maybe Kevin just found something new!

Can you also update Date as well?

[tomschenkjr]

@geneorama - I'm reruning the CI builds, but looks like it's just a conflict on the uploading process.

I made a couple of small comments in the code. Can you take a look at those and then also update this pull request to dev branch? I'll also merge #94 into dev for a test before pushing to master.

I didn't mean to include thelibrary(RSocrata), obviously had that in there while testing elsewhere. Updated the date.
Thanks for catching.

@geneorama - one more fix: can you adjust the target branch to dev?

[geneorama]

@tomschenkjr Yes, meant to use dev in the first place.

@geneorama - Oh, and duh, I forgot that I could have done it
