When a user encounters the "The issue has been updated by an other user while you were editing it." dialog, the "Private notes" box is set to unchecked, even if the user has checked the box. If that user selects "Apply my changes anyway" or "Add my notes and discard my other changes", they will submit a private note publicly, leading to much embarassment!

Steps to replicate:

Have user A start a note on an issue.
    Have user B start a note on an issue.
    Have user A submit their comment.
    Have user B submit their comment with the "private note" box checked.

User B will be informed that another comment has been posted. Do they
want to submit their changes anyway, or submit just the comment without
other changes?

User B selects "submit the comment without other changes".

Expected result:
User B's comment is private.

Actual result:
User B's comment is public.

On page reload, the "Private Notes" value should remain the same.
