Quill 2.0 clipboard matcher issue

[volser]

When paste plain text, clipboard matchers are not applied. because of this line

https://github.com/quilljs/quill/blob/develop/modules/clipboard.js#L87 new quill just interrupts converting delta

I believe need to apply all textMatchers in this case

Steps for Reproduction

1. visit https://codepen.io/volser/pen/pMxBOX
2. Paste text from plain text editor

Expected behavior: Clipboard handler should be called

Actual behavior: Was not called

Platforms: Windows, Chrome

Version: "2.0.0-dev.2"

Confirming I've come up against this too.

These lines are a short-circuit of the matcher functionality for text that doesn't include HTML:

The following line calls convertHTML which in turn calls traverse which actually applies the matchers

This is easily reproduced by:

• copying plain text from a text editor / browser console and pasting (no matchers fired)
• copying any text from a website or out of the quill editor itself and pasting (matchers fired)

The text copied from an html source will at minimum include a <meta charset> tag whereas plaintext does not, see the difference below (first result plaintext, second copied from html source)

Still appears to be a regression, even in the latest 2.0.0-dev.4.
