Summary:
We originally didn't do this because creating a DOM tree was loading images.
Using range.createContextualFragment seems to do it without the tree ever
being attached.
Accompanying changes to src/pro are here:
https://phab.nylas.com/D3300https://github.com/nylas/edgehill/compare/bengotow/draft-dom-transformations?expand=1
Also rename applyTransformsToDraft => applyTransformsForSending. Needed
a new name because the function signature has changed. AFAIK there are no
open source plugins using the old functions.
Test Plan: All specs updated
