The fix did not work for me, and while technically I do not have the war within quest done, according to the current build notes I'm not supposed to have to. Edit: it finally popped on its own, through the Tenno Guide. After failing to get the restart fix to work I activated the tenno guide, cleared the active quest(heart of Deimos), then I went through a random mission and when the mission was over, the tenno guide recommended that I activate the heart of Deimos quest, which I did, and then it worked.
