BUG: Selection & active RTE not cleared when component is removed programatically

[mcottret]

Version: 0.16.30

Are you able to reproduce the bug from the demo?

[x] Yes
[ ] No

Steps to reproduce:

• Select a text component in the demo's canvas
• The selection box & RTE appear
• Open the console
• Execute editor.setComponents('');
• The component is removed, but the selection box & RTE are still present (see attached screenshot)

What is the expected behavior?

When programatically removing a selected component with an active RTE, the selection & active RTE should be cleared.

What is the current behavior?

Component selection & RTE stay active on top of an unexisting component. Component selection disappears when clicked, but the RTE does not & causes an error.

Proposed solution:

• Execute the ComponentTextView's onDisable handler when it's removed
• Add a generic remove handler for components, removing them from selection if appropriate

As always, I'd be happy to take care of the PR if this looks good to you !

Are you able to attach screenshots, screencasts or a live demo?

[x] Yes (attach)
[ ] No
