Quill thinks the editor is blank if the first text was inserted with source=silent

[evansolomon]

If you have a blank Quill editor and insert text using source=silent, no text-change event is emitted. This means that the ql-blank class is not removed and the placeholder text is still displayed, so you end up with your content and the placeholder overlapping.
