Contact Request Tags and Lists does not work

Following the code example, tags are not applied to a contact when set.

The tag was created in SendX

```js
contactRequest.tags = ["sometagname"]; // DOES NOT WORK
```

Assuming that the ID for 'sometagname' is expected from the URL, e.g. https://app.sendx.io/audience/tag/details/12345678

```js
contactRequest.tags = ["12345678"]; // DOES NOT WORK
```


The above is also true for Lists
