[BUG] Composer change event is not fired when all text is deleted

[loomchild]

Describe the bug
Composer change event is not fired on empty text (for example, when I select all the text and delete it).

To Reproduce

1. Register a change handler on <nylas-composer> component, logging out all messages
2. When text is added or part of it deleted, the handler is correctly fire. However, if I delete all text, it's not fire.

(Please let me know if above is sufficient - I can provide a CodePen similar if necessary)

Expected behavior
Composer should fire change event when all text is deleted. I am uncertain if this event should also be fired with empty text during initialization.

Version:
1.1.6-canary.20in

Additional context
The issue seems to be in this line, because if (onchange) onchange(html) is only being run if html is not falsy.
