Fail to create issue if package.json present (and empty) in repository calling action

[juanitosvq]

The error described in #83 seems to happen if the repository calling the action contains a package.json (in my case, the file was empty):

/home/runner/work/_actions/JasonEtco/create-an-issue/v2/dist/index.js:32633
		throw jsonErr;
		^

}

I haven't checked to see what would happen if package.json contains some valid JSON.
