Fixes issue where vmaf plot was always ran if target-quality was set, this does not allow you to run vmaf plot without target-quality as it seems like vmaf plot was designed around target-quality at some point so --vmaf without --target-quality will do nothing. Decoupling the two seems like it will be a lot of work so I am adding this for now as it atleast closes #790 and the decoupling can happen later
