Fixed broken tests

The tests were failing because this was being used to check if the text existed inside `$el`
```javascript
$el.html().contains( "Full name" )
```
`contains()` only checks for child DOM elements and not text, `is()` checks if `$el` matches the provided jQuery selector, the `:contains()` selector matches elements that have the specified text within them

```javascript
$el.is( ":contains(Full name)" )
```
