[Bug] Cannot get a string value that represents an encoded JSON object

[tcarrio]

I have validated this will multiple payloads, and the only one that won't fail is an empty object.

Input	Success
{}	Yes
{"a":"b"}	No
{"name":"tcarrio"}	No

The entirety of the string has the quotations escaped, and the local Roxy server returns the values as you would expect to see them for it to be resolved correctly as a string value.

Example response JSON from the /flags endpoint (showing only the flag in question):

{
    "flagName": "dev.openfeature.object_flag",
    "expression": "\"{\"name\":\"OpenFeature\",\"version\":\"1.0.0\"}\"",
    "lastModifiedDate": "2022-11-17T00:50:01.549Z"
}

This likely has something to do with the string processing post response. With the empty object example I do resolve the value and can json_decode into an array.

Seems like so, at least using the string with double quotes. However, it worked when I defined the object string using single quotes, like this:

'"{\"name\":\"OpenFeature\",\"version\":\"1.0.0\"}"'

Test code:

class Container
{
    public $expressionFlag;

    public function __construct()
    {
        $this->expressionFlag = new RoxString('"{\"name\":\"OpenFeature\",\"version\":\"1.0.0\"}"');
    }
}

// ... All the $container instance setup

echo ">>> expressionFlag is " . $container->expressionFlag->getValue() . "\n"; // 

$decoded = json_decode($container->expressionFlag->getValue(), true);
echo ">>> decoded: " . $decoded;

Result logs:

>>> expressionFlag is "{\"name\":\"OpenFeature\",\"version\":\"1.0.0\"}"
>>> decoded: {"name":"OpenFeature","version":"1.0.0"}

In case I was using double quotes, the $decoded object was empty.

@tcarrio Can you please confirm that this solution works for you as well?

Closing this issue as the solution is one describe in the message above. In case solution will not work for some reason, we can re-open (or create another one) with updated issue details.
