Fixed bug on JSON metadata when ld+JSON is formatted wrong

[felipehertzer]

Hi @adbar,

I was testing the JSON metadata and I found this bug, the JSON is wrong, but it was causing an exception in the script. I saw your message about testing, as soon I have time I will contribute.

"author":{"@type":"Person","name":{"@type":"Person","name":"John Smiths"}}

Before:

AttributeError: 'dict' object has no attribute 'lower'

Now:

"author": "John Smiths"
