Zygo ribosome's `get` incorrectly returns JSONified `%result` for string entries

[MightyAlex200]

When using the get function in Zygomys, the %result of the returned hashmap will be surrounded by quotation marks if the entry is a string.

Example:

dna.json:

    "Zomes": [
        {
            "Name": "zygoStrBug",
            "Description": "Demonstrate how Zygomys strings are incorrectly JSONified in the get function",
            "CodeFile": "zygoStrBug.zy",
            "RibosomeType": "zygo",
            "Entries": [
                {
                    "Name": "sampleEntry",
                    "DataFormat": "string",
                    "Sharing": "public"
                }
            ],
            "Functions": [
                {
                    "Name": "createEntry",
                    "CallingType": "string",
                    "Exposure": "public"
                },
                {
                    "Name": "getEntry",
                    "CallingType": "string",
                    "Exposure": "public"
                }
            ]
        }
    ]

zygoStrBug.zy:

(defn genesis [] true)

(defn validateCommit [entryType entry header package sources] true)

(defn validatePut [entryType entry header package sources] true)

(defn createEntry [s] (commit "sampleEntry" s))

(defn getEntry [h] (hget (get h) %result))

test/sample.json:

{
    "Tests": [
        {
            "Convey": "Create an entry",
            "Zome": "zygoStrBug",
            "FnName": "createEntry",
            "Input": "Hello, world!",
            "Output": "%h%"
        },
        {
            "Convey": "Read an entry",
            "Zome": "zygoStrBug",
            "FnName": "getEntry",
            "Input": "%h%",
            "Output": "Hello, world!"
        }
    ]
}

Not sure because I don't actually know any Go but I think this line is the problem.

In the Javascript ribosome, I think the analogous line would be this one. This line uses a function that checks if the entry is actual JSON data before stringifying it.

I think the best solution for now would be to create a function in zygosome.go that does the same thing. A more long term solution (easier to support the addition of other ribosomes) would be to put the entry stringify function in a shared ribosome library.
