Cutting doesn't capture card section immediately following a list section

[kevinansfield]

When cutting content that includes a card section immediately following a list section, the card is not captured as part of the serialised mobiledoc in the clipboard's html attribute.

Example html when a non-card section separates the list and card sections:

<meta charset='utf-8'><div data-mobiledoc='{"version":"0.3.1","atoms":[],"cards":[["markdown",{"markdown":"markdown card"}]],"markups":[],"sections":[[3,"ul",[[[0,[],0,"list"]]]],[1,"p",[[0,[],0,"test"]]],[10,0],[1,"p",[[0,[],0,"test"]]]]}'><div><ul><li>list</li></ul><p>test</p><p>test</p></div></div>

Example html when a card section immediately follows a list section:

<meta charset='utf-8'><div data-mobiledoc='{"version":"0.3.1","atoms":[],"cards":[],"markups":[],"sections":[[3,"ul",[[[0,[],0,"list"]]]],[1,"p",[[0,[],0,"test"]]]]}'><div><ul><li>list</li></ul><p>test</p></div></div>

Initial testing appears to suggest the problem is in post.trimTo(range). I'm looking at creating a failing test case and fix.
