"TypeError: Cannot read property 'join' of undefined" on sharing error

I incorrectly attempted to share a recording with a description that included double quote characters. This resulted in the following error:

```
$ terminalizer share launch.yml
Please enter some details about your recording
? Title title
? Description ""
? Tags such as git,bash,game linux

/home/regis/venvs/node_modules/terminalizer/commands/share.js:201
return reject(body.errors.join('\n'));
^

TypeError: Cannot read property 'join' of undefined
```

This error is caused by the fact that `body` is a string, not an object. It is resolved by adding `body = JSON.parse(body);` at the beginning of the request callback. Would you like me to open a PR?

Start in commands/share.js at the request callback around line 201, where the code calls body.errors.join('\n'). Reproduce the sharing flow with a description containing double quotes and inspect the response type. Done means the response is handled as structured data and the same error no longer produces a TypeError.
