Adding a new link fails

[metsavir]

When a link is added right after checking some other link's URL, checked link is updated. Adding a new link fails.

Steps for Reproduction

1. Visit http://quilljs.com/playground/ (add 'link' to the toolbar)
2. Write link1 link2
3. Select link1 text, click the link button in the toolbar, save
4. Click link1 text to see the URL
5. Select link2 text, click the link button in the toolbar, save

Expected behavior:

link2 should be a link to URL link2.

Actual behavior:

link2 isn't a link. link1's URL is now link2.

Platforms:

Google Chrome 53.0.2785.143 (64-bit), OS X El Capitan

Version:

v1.0.6
