On a pristine form - the reset event will not include the EasyMDE text area value.

**Describe the bug**

If we include our target textarea in a form, and the add the `name` attribute, then we can treat the EasyMDE textarea like any form element and expect it to otherwise expect it to have the same behaviour as regular form elements.

When reseting a form, the event dispatched should include the current value of the text area. However, if it it is untouched there will be no value associated.

**nb.** The bug occurs for text areas declared like this:

```


Reset
Submit

const easymde = new EasyMDE({
element: document.getElementById('my-text-area'),
initialValue: 'I am initial value',
});

```

Text areas that are declared like this work fine:

```

I am initial value
Reset
Submit

const easymde = new EasyMDE({
element: document.getElementById('my-text-area')
});

```

**To Reproduce**
Reproduction here:

https://stackblitz.com/edit/easymde-tc8blv/?file=index.html

To see expected behaviour:

Click the second 'reset' button - this is a plain non-easymde text area in a form.
Note that the value of the text area is shown in the alert.

Now click the first reset button - there is no value for the text area.

**Expected behavior**

The initial value should treated as part of the reset event.

**Version information**
- OS: [e.g. Windows, MacOS]
- Browser: [e.g. Chrome 72]
- EasyMDE version: [e.g. 2.5.1]

**Additional context**

Note:

This problem only exists if passing in `initialValue` as part of the options to the `new EasyMDE(..)` call. If you put the initialValue in to the textarea it self like:

`I am the initial content` then it works fine.
