[BUG] Formbuilder triggers change event twice

[Sefriol]

Environment

Please provide as many details as you can:

• Hosting type
  • [ ] Form.io
  • [x] Local deployment
  • Version: 4.12.1-rc.18
• Formio.js version: 4.12.1-rc.18
• Frontend framework: latest
• Browser: Chrome
• Browser version:

Steps to Reproduce

1. Install vue-formio
2. Open Formbuilder
3. Add a component and save

Expected behavior

Change event should only trigger once

Observed behavior

It triggers twice

Example

It seem that there is already a component in formio that emits change event after component has been removed, updated or saved.

After emitting a change event in:

https://github.com/formio/vue-formio/blob/master/src/components/FormBuilder.ts#L67

there comes a second event change that is emitted in:

https://github.com/formio/vue-formio/blob/master/src/components/FormBuilder.ts#L62

Even if the line FormBuilder.ts#L67 is commented out, the event will still occur. So, is emitting this event separately necessary?

[Sefriol]

Workaround for a moment: Just track removeComponent, saveComponent instead.

EDIT: and addComponent
