Warning "no onClicked" when button component is used with @type="submit" and no click handler

[neojp]

Expected Behavior

Do not send a missing this.args.onClicked warning if component is used as button[type=submit].

Actual Behavior

A warning is sent for a missing this.args.onClicked function even if it's not necessary.

ember-styleguide/addon/components/es-button.js

Lines 13 to 18 in 0eb219f

	if(!this.args.onClicked) {
	// eslint-disable-next-line no-console
	console.warn(new Error('Button created with no onClicked'));
	} else {
	this._onClicked = this.args.onClicked;
	}

Steps to Reproduce

Add an es-button component with @type=submit and no @onClicked.

<EsButton @type="submit" @label="Search" />

For additional context, the error seems to be happening if the <form> element takes a submit event, which allows the user to press Enter to submit the form.

<form {{on "submit" this.submitForm}}>
  <button type="submit">Save</button>
</form>
