changes best_effort_json_encode to do not convert json to string

[kajedot]

When I was testing sending JSONs in arguments, I found out that everything is converted to the string. In consequence Seq, is interpreting JSON structures as a plain text. In this situation, we are loosing Seq features related to handling JSON data, like easy querying on JSON fields, folding, coloring etc. Therefore I changed best_effort_json_encode function. Now it is checking if a given parameter is a JSON object, and if it is, then it does not convert it to a string. If given argument is not a proper JSON structure (json.dumps throw TypeError), then it converts it to a string like it was before.

Before:

After:

I also added JSON objects to arguments in tests.
