Bug when last group before forced key frame is short. Just before a forced key frame we often get a foreshortened arf/gf group. In such a case, we do not want to update rc->last_boosted_qindex, which is used to define the Q range for the forced key frame itself. This gives a small average metrics gain for the YT and YT-HD sets (eg. YT SSIM +0.141%). Change-Id: Ie06698bc4f249e87183b8f8fb27ff8f3fde216d9
